Managing Users and User Groups
External user group requirements (egroup)
An external user group is a user group for which membership is not statically
configured, but is instead retrieved by running an external executable with the
name egroup. The egroup executable must be in the directory specified by
LSF_SERVERDIR.
This feature allows a site to maintain group definitions outside LSF and import
them into LSF configuration at initialization time.
The egroup executable is an executable you create yourself that lists group
names and users who belong to the group.
This executable must have the name egroup. When mbatchd is restarted, it
invokes the egroup executable and retrieves groups and group members. The
external executable egroup runs under the same account as mbatchd.
The egroup executable must write user names for the user groups to its
standard output, each name separated by white space.
The egroup executable must recognize the following command, since
mbatchd invokes external user groups with this command:
egroup -u user_group_name
where user_group_name is the name of the user group defined in the
executable egroup along with its members, and the user group is specified in
lsb.users.
