Hi, I'd like to use nscd for passwd+group caching. pam_ldap is configured and works (e.g. 'id foo' returns the correct user id if foo is present in ldap). If I start nscd manually (not started by default), 'id foo' returns 'No such user'. As soon as I stop nscd, 'id foo' starts working again. I suspect nscd is only looking at /etc/passwd because 'id root' always works (root is present in /etc/passwd). This is on a CentOS 5 system. Disabling SELinux did not help. I did not attach any config files purposefully because I don't know where to look for the problem and attaching nsswitch.conf, ldap.conf etc. would result in a huge post. Nevertheless, I will consider any information needed to diagnose the problem although I suspect that this a very simple configuration problem. Thank you very much :-) fs
