PRM User Initial Group Alternate Group(s)
------------------------------------------------------------------
guest OTHERS
user0 even_PRM_group
user1 odd_PRM_group
user2 even_PRM_group prime_PRM_group
user3 odd_PRM_group prime_PRM_group
user4 even_PRM_group
user5 Five
root PRM_SYS
For the users who are members of multiple netgroups, their initial and alternate groups are
cumulative. For example, user2 is in the even and prime netgroups, with initial groups
even_PRM_group and prime_PRM_group, respectively. In this situation, the netgroup names
are sorted (based on the ASCII dictionary), and the netgroup at the top of the sort list is used to
determine user2’s initial PRM group. Thus, because even_PRM_group comes before
prime_PRM_group, even_PRM_group is used as the initial group. All other PRM groups specified
in the netgroups’ user records become alternate groups.
Here the -u option limits the output to the prime netgroup:
#prmlist -u +prime
PRM User Initial Group Alternate Group(s)
------------------------------------------------------------------
user5 Five
user3 odd_PRM_group prime_PRM_group
user2 even_PRM_group prime_PRM_group
Recall that user5 is in multiple netgroups. Based on the cumulative effect of netgroup membership
for user2 and user3, one would expect user5 to show an initial group and at least one alternate
group. However, user5 has an explicit user record, which takes precedence over any netgroup’s
user records.
Displaying accessible PRM groups
Use the prmmove command or the prmrun command with no options to display the PRM groups
you can access. As root, you have access to all PRM groups. Thus, as root, these commands list
all configured PRM groups.
Displaying state and configuration information
To print current configuration, state, and mode information, use the command:
#prmconfig
PRM configured from file: /etc/prmconf
