Hi Joseph,
I've resolved this problem for myself by changind the order of lookups :
$>cat /etc/nsswitch.conf
group: pgsql files
passwd: pgsql files
....
but it'd be a good idea to compile add the ncsd (nis caching daemon).
then the file will look like this
group: cache files pgsql
etc...
as far as I looked at the code I think the problem is that there is no
failback when doing login_get_lastlog on other nis records but I've
found solution for me and I prefer not to patch the code (hope it gets
in stable releases sooner or later)
cheers,
valqk.
