Hello,
I am running 2.6.18-274.17.1.el5 with openldap-2.3.43-12.el5_7.10. Lately I've been seeing the following errors in /var/log/messages. Once this error starts it appears to almost freeze the server. I cannot connect via ssh and restarting services take minutes to restart if not restarting at all. My only option is to reboot the server. All is fine for a few days then it happens again.
nss_ldap: could not search LDAP server - Server is unavailable
This disconnects my samba shares and does not allow users to login to Windows anymore.
Can anyone help me with this issue?
Quick fix;
echo bind_policy soft >> /etc/ldap.conf
Long fix, look at the following directives added in nss_ldap version 241:
* new (undocumented) nss_reconnect_tries, nss_reconnect_sleeptime, nss_reconnect_maxsleeptime, nss_reconnect_maxconntries directives
Much longer fix, upgrade to 6 and us nslcd or sss.
