But, sysadm members have a reason, and I see no reason to increase their
overhead with local accounts.

I was planning for pam_ldap's pam_groupdn option. E.g. a 'sysadm' group.

I think it would be better to try and provide VCS commit access without shell
access. This is easy enough for subversion with mod_dav_svn.

How are we submitting to mdvsys? Command-line? API?

What permissions do packagers need that non-packager committer don't?

This is svn commit but no mdvsys access?

</I>
There is 'Account Admin' "system" group in LDAP, which allows any modification
to any users. But, should system administration necessarily mean all access in
all applications?
