Lustre discuss - Sep 2008 - l_getgroups: no such user

We are getting a bunch of:

l_getgroups: no such user ######

in our log files on the mds.
We keep our /etc/passswd and /etc/group in sync with the clusters  
that mount it.  Only one visulization workstation has users who are  
not in its list.

Problem is I don''t see any files owned by those users on the filesystem

find . -uid #####

Finds nothing,
Does lustre check if a user just cd''s to that directory?  Or is it  
for any user that logs in?
Is it safe to ignore these messages for non cluster users?

If you don''t need supplementary goups, you can just set the upcall to
NONE.  If you do need supplementary groups then you really do need to
unify and universally distribute the passwd/group database to all of the
clients and MDSes.
