Hi! I'm using CentOS 5.1 (x86_64) machines which authenticate using LDAP. At the start of booting I get messages like this: udevd[1158]: nss_ldap: failed to bind to LDAP server ldaps://ldap.server.example.com/: Can't contact LDAP server udevd[1158]: nss_ldap: reconnecting to LDAP server... udevd[1158]: nss_ldap: could not connect to any LDAP server as (null) - Can't contact LDAP server udevd[1158]: nss_ldap: failed to bind to LDAP server ldaps://ldap.server.example.com/: Can't contact LDAP server udevd[1158]: nss_ldap: reconnecting to LDAP server (sleeping 1 seconds)... This escaletes to 2, 4, 8, 16, 32, 64 seconds. After that (==timeouting for 2 minutes) booting continues without problem, so this is not really a showstopper, but inconvenient. Googling around revealed some fixes for Debian/Ubuntu. The bottom line i that udevd needs some user/group that is not in the local files but on the LDAP-server. The fix usually was adding this user (nvram, scanner ...) or group locally. The problem is, that on these systems after the last attempt something like udevd[1158]: lookup_group: error resolving group 'rdma': Illegal seek is printed out, makeing it easy to find the right group/user. Is there a way to get CentOS to a similar behaviour, making it easier to find the culprit?
There is a BUG with nss_ldap: https://bugzilla.redhat.com/show_bug.cgi?id=448014 We have this bug listed in our release notes: http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.2#head-447967c60eb305ef2c5dbbc3f4e8b3c4c5170632 You can try the nss_ldap from our testing repo for this bug: http://dev.centos.org/centos/5/ This may help with the problem.
