I tried building a later nss_ldap module on RHEL3 and was dogged with segmentation faults when performing lookups. This doesn't mean you are locked into using the shadow passwds given by NIS. I am using kerberos instead via your other instructions for Linux. Basically using NIS as the replacement for LDAP/AD in this case. http://blog.scottlowe.org/2007/01/15/linux-ad-integration-version-4/ BTW, it will generally fail on the first attempt if the NIS server can't be reached, but the second login try will succeed.

I'll update the article accordingly! Magnus,

I would still rather VMware update to a bugfree nss-library but at least we won't have to use local groups. Cheers, Magnus Scott,

Perhaps changing the order to UNIX first then Kerberos might help, if they aren't already in that order. Rob,

Any ideas?
