failed to bind to LDAP server ldap://<ldap server hostname>: Can't contact LDAP server: Transport endpoint is not connected no available LDAP server found: Can't contact LDAP server: Transport endpoint is not connected no available LDAP server found: Server is unavailable: Transport endpoint is not connected
Can ping ldap server from ldap client (vice versa as well)
Operating System: CentOS Linux 7 (Core) for both ldap server and client
Reviewed and compared /etc/nslcd.conf and /etc/openldap/openldap.conf on ldap server(source) and ldap client (destination).
Stopped both nslcd.service and slapd.service after Restarting ldap server yet still receiving failed to bind to LDAP server ldap://<ldap server hostname>: Can't contact LDAP server: Transport endpoint is not connected.
Do I need to check elsewhere? Requesting guidance to root cause. Thank you kindly.
