ARGUMENTS [Toc] [Back]
account_name
The name of a single account to act on. See
account_name_list for the name format.
account_name_list
A list of one or more names of accounts to act on. Note that
accounts are identified by principal names, so when you
create an account you supply a principal name for the
account name.
Supply the names as follows:
+ Fully qualified account names in the form
/.../cell_name/account_name, /.:/account_name, or
account_name@cell_name.
+ Cell-relative account names in the form account_name.
These names refer to an account in the cell identified
in the _s(sec) convenience variable, or if the _s(sec)
convenience variable is not set, in the local host's
Hewlett-Packard Company - 1 OSF DCE 1.1/HP DCE 1.8 PHSS_26394-96

default cell.
Do not mix fully qualified names and cell-relative names in
a list. In addition, do not use the names of registry
database objects that contain account information; in other
words, do not use account names that begin with
/.:/sec/account/.
cell_name The name of a specific cell (or /.: for the local cell) in
which to catalog accounts.
operation The name of the account operation for which to display help
information.
DESCRIPTION [Toc] [Back]
The account object represents registry accounts. Although an account
is associated with one principal, one group, and one organization, it
is identified by the principal's primary name. Alias names are
differentiated for principals, so one principal can have multiple
accounts under different alias names.
When this command executes, it attempts to bind to the registry server
identified in the _s(sec) variable. If that server cannot process the
request or if the _s(sec) variable is not set, the command binds to
either an available slave server or the master registry server,
depending on the operation. Upon completion, the command sets the
_b(sec) convenience variable to the name of the registry server it
bound to.
ATTRIBUTES [Toc] [Back]
The account object supports the following two kinds of attributes:
+ Account attributes may or may not have default values. They
assume a default value or a value set by administrators.
+ Policy attributes regulate such things as account and password
lifetimes for all accounts associated with a particular registry.
Policy attributes have registry wide default values. They always
assume the most restrictive value whether it is the registry wide
default value or a value set for an individual account.
Account Attributes [Toc] [Back]
acctvalid {yes | no}
A flag set to determine account validity. Its value is
either yes or no. An account with an acctvalid attribute
set to no is invalid and cannot be logged in to. The
default is yes.
Hewlett-Packard Company - 2 OSF DCE 1.1/HP DCE 1.8 PHSS_26394-96
account(1m) Open Software Foundation account(1m)
client {yes | no}
A flag set to indicate whether the account is for a
principal that can act as a client. Its value is either yes
or no. If you set this flag to yes, the principal is able
to log in to the account and acquire tickets for
authentication. The default is yes.
created creators_name ISO_timestamp
A list of two items. The first is the principal name of the
creator of the account, the second is an ISO timestamp
showing the time of creation. This attribute is set by the
system at the time of account creation and cannot be
specified or modified.
description string
A text string (limited to the Portable Character Set)
typically used to describe the use of the account. The
default is the empty string ("").
dupkey {yes | no}
A flag set to determine whether tickets issued to the
account's principal can have duplicate keys. Its value is
either yes or no. The default is no.
In DCE this attribute is currently only advisory. However,
Kerberos clients and servers make use of it when they
interact with a DCE Security server.
expdate ISO_timestamp
The date on which the account expires. To renew the
account, change the date in this field. To specify the
time, use an ISO-compliant time format such as CCYY-MM-DD-
hh:mm:ss or the string none. The default is none.
forwardabletkt {yes | no}
A flag set to determine whether a new ticket-granting ticket
with a network address that differs from the present
ticket-granting ticket's network address can be issued to
the account's principal. The proxiabletkt attribute
performs the same function for service tickets. Its value
is either yes or no. The default is yes.
In DCE this attribute is currently only advisory. However,
Kerberos clients and servers make use of it when they
interact with a DCE Security server.
goodsince ISO_timestamp
The date and time the account was last known to be in an
uncompromised state. Any tickets granted before this date
are invalid. The value is an ISO timestamp. When the
account is initially created, the goodsince date is set to
Hewlett-Packard Company - 3 OSF DCE 1.1/HP DCE 1.8 PHSS_26394-96
account(1m) Open Software Foundation account(1m)
the current date. Control over this date is especially
useful if you know that an account's password was
compromised. Changing the password can prevent the
unauthorized principal from accessing the system again using
that password, but the changed password does not prevent the
principal from accessing the system components for which
tickets were obtained fraudulently before the password was
changed. To eliminate the principal's access to the system,
the tickets must be cancelled.
The default is the time the account was created.
group group_name
The name of the group associated with the account. The
value is a single group name of an existing group in the
registry. This attribute must be specified for the account
create command; it does not have a default value.
If a group is deleted from the registry, all accounts
associated with the group are also deleted.
home directory_name
The file system directory in which the principal is placed
at login. The default is the / directory.
lastchange principal_name ISO_timestamp
A list of two items. The first is the principal name of the
last modifier of the account; the second is an ISO timestamp
showing the time of the last modification. This attribute
is set by the system whenever the account is modified; it
cannot be set or modified directly. The initial value
consists of the principal name of the creator of the account
and the time the account was created.
organization organization_name
The name of the organization associated with the account.
The value is a single organization name of an existing
organization in the registry. This attribute must be
specified for the account create command; it does not have a
default value.
If an organization is deleted from the registry, all
accounts associated with the organization are deleted also.
password password
The password of the account. This attribute must be
specified for the account create command; there is no
default value. This attribute is not returned by an account
show command.

account(1m) Open Software Foundation account(1m)
postdatedtkt {yes | no}
A flag set to determine if tickets with a start time some
time in the future can be issued to the account's principal.
Its value is either yes or no. The default is no.
In DCE, this attribute is currently only advisory. However,
Kerberos clients and servers make use of it when they
interact with a DCE Security server.
proxiabletkt {yes | no}
A flag set to determine whether a new ticket with a
different network address than the present ticket can be
issued to the account's principal. The forwardabletkt
attribute performs the same function for ticket-granting
tickets. Its value is either yes or no. The default is no.
In DCE, this attribute is currently only advisory. However,
Kerberos clients and servers make use of it when they
interact with a DCE Security server.
pwdvalid {yes | no}
A flag set to determine whether the current password is
valid. If this flag is set to no, the next time a principal
logs in to the account, the system prompts the principal to
change the password. (Note that this flag is separate from
the pwdexpdate policy, which sets time limits on password
validity.) Its value is either yes or no. The default is
yes.
renewabletkt {yes | no}
A flag set to determine if the ticket-granting ticket issued
to the account's principal can be renewed. If this flag is
set to yes, the authentication service renews the ticketgranting
ticket if its lifetime is valid. Its value is
either yes or no. The default is yes.
In DCE this attribute is currently only advisory. However,
Kerberos clients and servers make use of it when they
interact with a DCE Security server.
server {yes | no}
A flag set to indicate whether the account is for a
principal that can act as a server. Its value is either yes
or no. This flag should be yes for any server that engages
in authenticated communications. The default is yes.
shell path_to_shell
The path of the shell that is executed when a principal logs
in. The legal value is any shell supported by the home cell.
The default value is the empty string ("").
Hewlett-Packard Company - 5 OSF DCE 1.1/HP DCE 1.8 PHSS_26394-96
account(1m) Open Software Foundation account(1m)
stdtgtauth {yes | no}
A flag set to determine whether service tickets issued to
the account's principal use the standard DCE ticket-granting
ticket authentication mechanism. Its value is either yes or
no. The default is yes.
Policy Attributes [Toc] [Back]
maxtktlife relative_time
The maximum amount of time that a ticket can be valid. To
specify the time, use the Distributed Time Service (DTS)
relative time format ([-]DD-hh:mm:ss). When a client
requests a ticket to a server, the lifetime granted to the
ticket takes into account the maxtktlife set for both the
server and the client. In other words, the lifetime cannot
exceed the shorter of the server's or client's maxtktlife.
If you do not specify a maxtktlife for an account, the
maxtktlife defined as registry authorization policy is used.
maxtktrenew relative_time
The amount of time before a principal's ticket-granting
ticket expires and that principal must log in to the system
again to reauthenticate and obtain another ticket-granting
ticket. To specify the time, use the DTS relative time
format ([-]DD-hh:mm:ss). The lifetime of the principal's
service tickets can never exceed the lifetime of the
principal's ticket-granting ticket. The shorter you make
maxtktrenew, the greater the security of the system.
However, since principals must log in again to renew their
ticket-granting ticket, the time specified needs to balance
user convenience against the level of security required. If
you do not specify this for an account, the maxtktrenew
lifetime defined as registry authorization policy is used.
This feature is not currently used by DCE; any use of this
option is unsupported at the present time.
See the OSF DCE Administration Guide for more information about
account attributes.
OPERATIONS [Toc] [Back]
account catalog
Returns a list of the names of all accounts in the registry. The

-simplename
Returns a list of account names in the registry without
prepending the name of the cell.
The catalog operation returns a list of the names of all accounts in
the local registry database. Use the cell_name argument to return a
list of accounts in another cell's registry. By default, fully
qualified names are returned in the form cell_name/account_name. Use
the -simplename option to return the names without the cell name in
the form account_name.

account create
Creates a new account in the registry database. The syntax is as
follows:
account create account_name_list
-mypwd password
-password password
-group group_name
-organization organization_name
[-attribute attribute_list | -attribute value]
Options [Toc] [Back]
-attribute value
As an alternative to using the -attribute option with an
attribute list, you can specify individual attribute options
by prepending a hyphen (-) to any attributes listed in the
ATTRIBUTES section of this reference page.
-attribute attribute_list
Allows you to specify attributes by using an attribute list
rather than individual attribute options. The format of an
attribute list is as follows:
{{attribute value}...{attribute value}}
-group group_name
The name of the group to associate with the account. See
Account Attributes for the format of a group name.
-mypwd password
Your privileged password. You must enter your privileged
password to create an account. This check prevents a
malicious user from using an existing privileged session to
create unauthorized accounts. You must specify this option
on the command line; it cannot be supplied in a script.
-organization organization_name
The name of the organization to associate with the account.
See Account Attributes for the format of an organization
name.
-password password
The account password. See Account Attributes for the format
of a password.
The create operation creates a new account. The account_name_list
argument is a list of names of principals for which the accounts are
Hewlett-Packard Company - 8 OSF DCE 1.1/HP DCE 1.8 PHSS_26394-96
account(1m) Open Software Foundation account(1m)
to be created. This operation returns an empty string on success.
You must specify the group, organization, password, and mypwd
attributes on the command line (either in an attribute list or with
attribute options). The attributes specified are applied to all of the
accounts created.
To protect the account password being entered, the account create
command can be entered only from within dcecp. You cannot enter this
command from the operating system prompt by using dcecp with the -c
option.
Before you can create a new account, you must create a principal by
using the principal create command. Then you must add the principal
to an existing group and organization using the group add and
organization add commands.
Privileges Required [Toc] [Back]
You must have the following permissions:
+ gmau (groups, mgmt_info, auth_info, and user_info) permissions to
the principal named in the account
+ rtM (read, test, Member_list) permissions to the organization
named in the account
+ tM (test, Member_list) permissions to the group named in the
account
+ r (read) permission on the registry policy object.

account delete
Deletes existing accounts from the registry. The syntax is as
follows:
account delete account_name_list
The delete operation deletes existing accounts from the registry. The
argument is a list of names of accounts to be deleted. If the
accounts do not exist, an error is generated. This operation returns
an empty string on success.
Privileges Required [Toc] [Back]
You must have rmau (read, mgmt_info, auth_info, user_info) permissions
for the principal named in the account.
Examples [Toc] [Back]
dcecp> account delete john_hunter

account generate
Randomly generates a password for a named account. The syntax is as
follows:
account generate account_name
To run the account generate command, the pwd_strength server must be
running, the principal identified by account_name must exist, and the
pwd_mgmt_binding and pwd_val_type Extended Registry Attributes must be
attached to that principal. Otherwise, an error is generated. The
command returns a randomly generated password on success.
See the OSF DCE Administration Guide for more information about the
pwd_strength server.
After the password is generated, run the account create command to
establish the account. Supply the randomly generated password as the
account's password (using the -password option).

account help
Returns help information about the account object and its operations.
The syntax is as follows:
account help [operation | -verbose]
Options [Toc] [Back]
-verbose Displays information about the account object.
Used without an argument or option, the account help command returns
brief information about each account operation. The optional operation
argument is the name of an operation about which you want detailed
information. Alternatively, you can use the -verbose option for more
detailed information about the account object itself.
Privileges Required [Toc] [Back]
No special privileges are needed to use the account help command.

-attribute value
As an alternative to using the -change option with an
attribute list, you can specify individual attribute options
by prepending a hyphen (-) to any attributes listed in the
ATTRIBUTES section of this reference page.
-change attribute_list
Allows you to modify attributes by using an attribute list
rather than individual attribute options. The format of an
attribute list is as follows:
{{attribute value}...{attribute value}}
-mypwd password
Lets you supply your privileged password when changing
policy or administration data. You must enter your
privileged password to change an account password;
otherwise, the -mypwd option is optional. This check
prevents a malicious user from using an existing privileged
session to modify passwords of existing accounts.
The modify operation modifies account attributes. The -add and -remove
options are not supported because the attributes created when the
account is created cannot be deleted, nor can additional attributes be
added. To change an account attribute, supply the new value in an
attribute list or as an individual attribute option. This operation
returns an empty string on success.
When an account's password is being modified, in order to protect the
password being entered, you can execute the account modify command
only from within the dcecp program; you cannot execute it from the
operating system prompt using dcecp with the -c option.
Privileges Required [Toc] [Back]
You must have rm (read, mgmt_info) permissions for the principal named

account(1m) Open Software Foundation account(1m)
account show account_name_list [-policies | -all]
Options [Toc] [Back]
-policies Returns only account polices.
-all Returns account attributes followed by account policies.
The show operation returns an attribute list describing the specified
accounts. The argument is a list of names of accounts to be operated
on. If more than one account is given, the attributes and policies
are concatenated and a blank line inserted between accounts. The
-policies option lets you return the policies of the account instead
of the attributes. The -all option returns the attributes followed by
the policies.
Attributes and policies are returned in lexical order. If the account
has no policies, the operation displays the string nopolicy.
The policies that are actually in effect can be different from the
account policies due to conflicts with registry wide policies. If this
is the case, the show operation alters the attribute structure on
output to include an effective tag and the effective value, much in
the same way organization show does.
