I am receiving the error:

Unable to LUM add/modify 'admin'

during our autoyast build of new servers (oes2sp2a and sles10sp3) - haven't seen this in previous builds (oes2sp1b and sles10sp2)....

It looks like it actually configures OK... and only delay the build 5 secs as it warns and counts down before continuing.
Lum appears to be working (at least id <user> shows expected results and lum group membership, etc. all OK)

Wondering if this is just an over zealous 'error' report when it is finding a pre-created user or group...?

Anyone else seeing this?
