Chapter 6. Troubleshooting
6.1. Common Installation Problems
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 www.domain.com, and make sure the server is listed in the DNS. If that does not work, check the IP address.
6.1.2. Problem: The port is in use
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.
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.
