Common Installation Problems
7.7.2.2. 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.
Solution
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.
7.7.2.3. Problem: Forgotten Directory Manager DN and password
Solution.
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.
