The /etc/default/rpc.nisd file is set up to use a local LDAP server at port 389. If this is not correct in your configuration, establish a new value for the preferredServerList attribute. For example, to use an LDAP server at IP address 192.0.0.1 and port 65535, you specify the following.
preferredServerList=192.0.0.1:65535 |
