We're suddenly experiencing an LDAP connection issue with our SLES 10 SP2 server and our Netware 6.5 server which is hosting LDAP services. SLES's Messages log reads:

/usr/sbin/namcd[]: ldap_initconn: LDAP bind failed, trying to connect to alternative LDAP server

Both servers have been re-booted which may have triggered the issue. Our engineer who is unavailable suggests the possiblity of a certificate issue. We're pinch-hitting for him so can someone point us in the right direction? Thanks for any help.
