Do you have "nss_initgroups_ignoreusers" set in /etc/ldap.conf? It could be that you are missing a user in that list? Ours look like:
nss_initgroups_ignoreusers root,ldap,named,avahi,haldaemon,dbus,radvd,tomcat,radiusd,news,mailman,nscd,gdm Or do you have anything in /etc/nsswitch.conf doing "ldap files" rather than "files ldap"? Looking at my running udevd on a RHEL5.5 box I see: t# lsof -p 657 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME udevd 657 root cwd DIR 253,0 1024 2 / udevd 657 root rtd DIR 253,0 1024 2 / udevd 657 root txt REG 253,0 61864 65609 /sbin/udevd udevd 657 root mem REG 253,0 139416 28676 /lib64/ld-2.5.so udevd 657 root mem REG 253,0 95464 28733 /lib64/libselinux.so.1 udevd 657 root mem REG 253,0 247496 28731 /lib64/libsepol.so.1 udevd 657 root mem REG 253,0 1718120 28683 /lib64/libc-2.5.so udevd 657 root mem REG 253,0 23360 28689 /lib64/libdl-2.5.so udevd 657 root mem REG 253,0 53880 28698 /lib64/libnss_files-2.5.so udevd 657 root 0u CHR 1,3 1634 /dev/null udevd 657 root 1u CHR 1,3 1634 /dev/null udevd 657 root 2u CHR 1,3 1634 /dev/null udevd 657 root 3u unix 0xffff81022dff1c00 1649 socket udevd 657 root 4u sock 0,5 1650 can't identify protocol udevd 657 root 5r FIFO 0,6 1660 pipe udevd 657 root 6w FIFO 0,6 1660 pipe udevd 657 root 7r DIR 0,10 0 541 inotify Notice that the only libnss library open is for files? I'm guessing that my server is resolving whatever udevd needs from files... I'd recommend always leaving "files" first.

Can't contact LDAP Server We get this through sleeps numerous sleeps - though it finally fails and the boot process begins. I have read a few bugs on this but it is in 5.2 and I'm running 5.7.
