Description of problem: During boot time, as udev is creating devices, if it comes across a device without a GROUP= option, it attempts to assign it the group "nogroup". Normally this silently fails, as there is no "nogroup" entry in Fedora's stock /etc/group. However, if in nsswitch.conf, "group" is set to "files ldap", udev will try to use nss_ldap to contact the LDAP server to resolve "nogroup" to a GID. Since udev is started way before the network at boot time, it cannot contact the LDAP server and you get several errors such as: vol_id[972]: nss_ldap: failed to bind to LDAP server ldap://servername: Can't contact LDAP server Searching Google, I found Mandriva's (and IMO the best) solution was to add a "nogroup" entry to the stock /etc/group (see link), although hacking udev to use another default group name, or simply adding a GROUP= option to every record in /etc/udev/rules.d/* may also fix the problem. http://www.linuxfordummies.org/index.php?topic=378.msg617#msg617 Version-Release number of selected component (if applicable): FC5test3 How reproducible: Always Steps to Reproduce: 1. Add "group = files ldap" to nsswitch.conf 2. Ensure there is no "nogroup" entry in /etc/group 3. Boot the system Actual results: Lots of nss_ldap errors as example above Expected results: udev starts silently and does not require network access. Additional info:
I should also mention that adding a "nogroup" entry to /etc/group DOES fix the entire problem. I didn't explicitly mention that before.
should be fixed with latest udev updates...
