title: Sonatype Nexus - can not login anymore with admin user
body: <p>I have a Sonatype Nexus installed and I have the default user admin / admin123.
  Now I changed the Authenticating Realm to LDAP and removed <code>XML Authenticating Realm</code> and <code>XML Authorizing Realm</code>. LDAP is not working and my admin account is also not working. I think it is because I disabled the XML Realm. How can I enable this? I have full access to the filesystem. The password can not be the problem, I did not change it.</p>
  
  <p>So I can not login anymore. What can I do?</p>
  
  <p>Best Regards, Tim.</p>
