Invalid DN syntax or naming violation

I’m installing Openfire for the first time. I’ve setup an openldap server on another machine. When I try to test the openfire openldap settings, I get the following error :

Invalid DN syntax or naming violation.

Server Type: OpenLDAP

Host: [MY IP]

Base DN: dc=[MY-DOMAIN],dc=local

Authentication DN: admin

Password: [LDAP ADMIN PW]

Any suggestions?
