7.2. Common Installation Problems

Clients cannot locate the server
First, try using the host name. If that does not work, use the fully qualified name (such as
www.domain.com), and make sure the server is listed in the DNS. If that does not work, use
the IP address.
If your NIS domain is different from your DNS domain, the fully-qualified host and domain
name presented by the installer may be incorrect. These values must be corrected to use the DNS
domain name.
The port is in use
You probably did not shut down a server before you upgraded it. Shut down the old server, then
manually start the upgraded one.
Another installed server might be using the port. Make sure the port you have chosen is not
already being used by another server.
LDAP authentication error causes install to fail
If you are installing Directory Server in a network that uses NIS naming rather than DNS nam-
ing, you may get the following error, with incorrect.DNS.address replaced by the DNS
address you attempted to use:
ERROR: Ldap authentication failed for url
ldap://incorrect.DNS.address
