      Set LdapExtLoginModule with options like:

      ...
<module-option name="java.naming.provider.url" value="ldap://localhost:10389"/>
<module-option name="baseCtxDN" value="ou=myOrgUnit,o=organization,dc=jboss,dc=org"/>
...

      => authentication passes

      Change these options like:

      ...
<module-option name="java.naming.provider.url" value="ldap://localhost:10389/o=organization,dc=jboss,dc=org"/>
<module-option name="baseCtxDN" value="ou=myOrgUnit"/>
...

      => authentication fails

      Set LdapExtLoginModule with options like: ... <module-option name= "java.naming.provider.url" value= "ldap: //localhost:10389" /> <module-option name= "baseCtxDN" value= "ou=myOrgUnit,o=organization,dc=jboss,dc=org" /> ... => authentication passes Change these options like: ... <module-option name= "java.naming.provider.url" value= "ldap: //localhost:10389/o=organization,dc=jboss,dc=org" /> <module-option name= "baseCtxDN" value= "ou=myOrgUnit" /> ... => authentication fails

      In case when part of DN is placed in LDAP URL instead of baseCtxDN then authentication fails (see [1] for details about this URL) in LdapExtLoginModule. Authentication is provided by binding with user DN and password, but in this case user DN does not include DN part from LDAP URL which leads to fail.
