userdel()

NAME

userdel - Deletes a user login account from the system.

SYNOPSIS

SVE: /usr/sbin/userdel [-r] login POSIX: /usr/sbin/userdel [-D] [-r] [-R] [-t type] [-P] [-x extended_option] login

OPTIONS

-D When enhanced security mode is enabled this option deletes the user account from /etc/passwd file and the enhanced security protected password database. -r Removes a users home directory from the system. This directory must exist and must be owned by the user whose login account is being deleted. -R When enhanced security is enabled, retires the account without deleting entries from the databases or removing home directories. -t type Removes a local plus (+) or local minus (-) NIS user from the user database. The value of the type parameter can be + or -. -P Removes PC accounts only, without deleting the users existing UNIX account. -x extended_option [extended_option]... Extended_options are of the form attribute=value. You may enter any number of extended options (within the character limit of the command line) by separating each option with a space. Alternatively, they may be entered separately following the -x switch. Note that some extended options are only available under specific system environments. The following sets of extended_option attributes are available: local=0|1 The value 1 indicates that the account to be deleted is local. The value 0 indicates that the account is to be deleted from some other database, either NIS or LDAP. distributed=0|1 The value 1 indicates that the account to be deleted is an NIS user account. You must be on the NIS master to delete an NIS user. ldap=0|1 The value 1 indicates that the account to be deleted is an LDAP account. LDAP must be configured, and you must be on the LDAP server or on an LDAP client with permission to modify the LDAP database. The following extended_option attribute is available for PC group administration if the Advanced Server for UNIX (ASU) is configured and running: pc_synchronize=0|1 The value of the pc_synchronize=n attribute can be 0 or 1. If set to 1, both PC and UNIX accounts will be affected by delete operations. If set to 0, only UNIX accounts will be affected and by delete operations and the PC account will be unaffected.

DESCRIPTION

The userdel command is part of a set of command line interfaces (CLI) that are used to create and administer user accounts on the system. When The Advanced Server for UNIX (ASU) is installed and running, the userdel command can also be used to administer PC accounts. Accounts can also be administered with the /usr/bin/X11/dxaccounts graphical user interface (GUI) or the sysman(8) Accounts menu. Different options are available depending on how the local system is configured: · In the default UNIX environment, user account management is compliant with the IEEE POSIX Standard P1387.3. · If enhanced (C2) security is configured, additional options and extended options can be used. · The CLI is backwards-compatible, so all existing local scripts will function. However, you should consider testing your account management scripts before using them. The userdel command deletes a user's login account from the system and makes the login-related changes in the appropriate system files determined by the current level of security. Additionally, the files and directories contained under the user's home directory can be removed from the system. With the -x option, the system administrator can specify extended options, such as whether the user login account to be deleted is local, resides in the NIS master database, or resides in the LDAP database. If -x option is not specified, the user login account is deleted from the appropriate database as specified by the system defaults. The default behavior on the system for the userdel command is as follows: local=1, distributed=0,and ldap=0. With these values, the system deletes the user from the local database. Certain combinations of these settings are incompatible and produce an error: it is invalid to set all of these values to 0 or set more than one of them to 1. When NIS or LDAP are available, the user may have secondary group memberships in more than one type of group. The user is always deleted from all secondary groups of the same type. If a member of groups of another type, the user will also be removed unless there is a user account with the same name in the corresponding database. For example, an LDAP user may have been given secondary membership in a local group. When the LDAP user is deleted, membership in the local group is also removed unless there is a local user with the same name.

RESTRICTIONS

Note the following restriction that applies to this release: You must have superuser privilege to execute this command.

EXIT STATUS

The userdel command exits with one of the following values: 0 Success. 1 Failure. 2 Warning.

EXAMPLES

1. The following example removes the local plus (+) user, newuser1: % userdel -t + newuser1 2. The following example removes the NIS user, newuser4, from the NIS master database: % userdel -r xyz 3. The following example deletes the UNIX account for studentB, removing the home directory and its corresponding PC account. % userdel -r -x pc_synchronize=1 studentB

FILES

The userdel command operates on files for the specific level of system security.
