Is it necessary to remove the ldb file, or does a simple restart 'fix'
things ?
I could try that next time around when a user calls me, thought to clear
the cache to be
sure...

Is it possible for you to raise the log level, or would that slow down
your production environment too much ?
In that case do you have any hints on how we could reproduce this
issue ? Have you notice if it happens periodically, or after specific
events ?
I have asked the users, who had this problem recurring, to call me,
I'll turn on debug
log at that time.
BTW, to troubleshoot an unrelated problem, I set the debug level to 0xFFF0, is this
overkill?

[nss]
debug_level = 0xFFF0
[pam]
debug_level = 0xFFF0

Thanks,
Simo.
