SYMPTOMS
A Network Information Service (NIS) client runs the &quot;ls -l&quot; UNIX command or a similar request that requires user and group information from NIS. If the local site does not contain any domain controllers (DCs) for the child domains, the NIS client may experience slow performance in the execution of the command.

Note Long delays that can cause a time-out for NIS operations can also occur if the DNS and NIS servers are located on different computers. These delays occur especially if the link between these computers is not fast enough. When the link is not fast enough, NIS commands must follow the LDAP referrals to the Forest and Domain (cross-site) DNS zones. Notice that, although this symptom resembles the one that is described earlier, this behavior will not change when you apply the hotfix in this article. To work around this behavior, use one or both of the following methods:
 * Reconfigure the net so that the servers are on the same computer.
 * Reconfigure the net so that the servers are linked by fast links.

Additionally, when you run the ypcat command on an NIS server, users might receive the following error message:

Call failed. : RPC: Unable to send; errno = no error string available

This problem occurs even if the rpcinfo -p command provides correct information.



CAUSE
This problem occurs when the local site does not have any DCs for the child domains. Therefore, it must follow referrals to complete the Lightweight Directory Access Protocol (LDAP) query. When the NIS client chases the referrals, the ypmatch command may take some time to be completed.
