roleadm(1M) roleadm(1M)
NAME
roleadm - noninteractive editing of role-related information in RBAC databases
SYNOPSIS
[comments]
[role]
DESCRIPTION
is a noninteractive command that allows users with the appropriate authorization to modify and list the role information in and
See rbac(5) for information on these RBAC databases.
HP recommends that only the and commands be used to edit and view the RBAC databases. Do not edit the RBAC files directly.
Options
recognizes the following options:
Add a role to the system list of valid roles.
Appends a line in file with rolename. You can enter an optional comment after the role.
Remove a role from the system list of valid roles.
If role is present in remove entry. If role is not present, then returns an error code; see
Change the name of a role.
This option causes a modification of the RBAC databases and replacing each occurrence of oldrolename with newrolename.
Assign a role to a user or a group.
First verifies that the user is a valid user, and the role is present in the file. When this is the case, the role is appended to
the user->role mapping in the file. If user argument has an ampersand at the beginning (such as &users), then it is assumed that
what follows after the ampersand is a group name - the ampersand must be shell escaped or put in quotes such as users or "&users".
An administrator may specify a default set of roles by assigning roles to the keyword. If a user is not otherwise explicitly
assigned roles in the database, he or she will be given roles assigned to the role.
Revoke a role from the specified user.
If no role is specified, then all roles are revoked for the given user. (The user entry is removed from If user argument has an
ampersand at the beginning (such as &users), then it is assumed that what follows after the ampersand is a group name - the amper-
sand must be shell escaped or put in quotes such as users or "&users".
List user and role information from the RBAC databases, and
If neither nor are specified, then list all the users with assigned roles.
If is specified, then only the role(s) of the specified user will be listed. If user has an ampersand at the beginning (such as
&users), then it is assumed that what follows after the ampersand is a group name - the ampersand must be shell escaped or put in
quotes such as users or "&users". If only is specified, then only list the user(s) assigned to the specified role. If both and are
specified, then the entry with the user username and role rolename will be listed, if it exists.
If the specified user does not exist in the system and there exists the special user, in the database, then the roles listed for the
specified user will be those of the user. In the event that there is more than one user defined in the database, the system will
recognize only the last one.
If is specified, then all the roles in the roles database, will be listed. When is specified, no other argument will be taken by
