Making sure you can connect using a browser

Kerberos processes names and not IP addresses. The IP address of your PC must map to the name of the service you intend to use.

Attempt to connect to the station using a fully-qualified domain name: http://some.domain.com/somepage, where
some.domain.com/somepage is the LDAP server’s domain name and home page name.
If you are unable to connect, edit your client PC’s hosts file to add an entry similar to:
nnn.nnn.nnn.nnn some.domain.com,where nnn.nnn.nnn.nnn is the IP address of the LDAP server,and some.domain.com is the domain name of the server.

For example,172.16.10.10 kerbtest2.mydomain.net
This Ip address maps to the Kerberos service associated with kerbtest2 on mydomain.net.
