Chapter 6. Troubleshooting

This chapter contains basic troubleshooting information. For information on using the Directory Server, see the Red Hat Directory Server 10 Administration Guide.

6.1. Common Installation Problems

There are several common problems that can come up during the setup process, generally relating to network or naming problems. These problems and workarounds and solutions are described below.

6.1.1. Problem: Clients cannot locate the server


First, modify the host name. If that does not work, use the fully-qualified domain name, like, and make sure the server is listed in the DNS. If that does not work, check the IP address.

If the NIS domain is not the same as your DNS domain, check your fully-qualified host and domain name.

6.1.2. Problem: The port is in use

When setting up a Directory Server instance, you receive an error that the port is in use. This is very common when upgrading or migrating an existing server.

This error means that you did not shut down the existing server before beginning the upgrade or migration. Shut down the existing server, and then restart the upgrade process.

If this occurs during a setup process, it may mean another server is already using this port. Verify that the port you selected is not in use by another server.

6.1.3. Problem: Forgotten Directory Manager DN and password


By default, the Directory Manager DN is cn=Directory Manager. If you forget the Directory Manager DN, you can determine it by checking the nsslapd-rootdn attribute in the dse.ldif file, in the /etc/dirsrv/slapd-instance_name directory.
