Recently, in the company where I work, we have had a general system crash and we are figuring out the causes. Our machines are configured for LDAP authentication plus some local users in some of them. LDAP authentication works fine but we have found, from the log, that also for local users there are some LDAP queries and we think that this could be related to the crash. I am working on this problem, changing nsswitch.conf, pam modules and so on, but I can't get rid of this LDAP call for local users. Does anyone have any idea on how to stop LDAP queries for local users?
Thank you very much in advance.
In our machine is installed SuSE Linux 11 SP2 and OpenLDAP 2.4. This is nsswitch.conf
passwd: compat group: files ldap hosts: files dns networks: files dns passwd_compat: ldap group_compat: ldap
This is the log taken from the LDAP server after a login attempt on another machine from a user called guest which is local to that machine
