I cant get racadm to set my Role Groups it returns -  ERROR: The specified object value is not valid

I have tried the command remotely and locally and it does not matter, this is on a DELL R710 DRAC Version 1.70

The syntax as follows:

racadm config -g cfgLDAPRoleGroup -o cfgLDAPRoleGroupDN -i 1 CN=blah.blah.blah,OU=groupblah,DC=domain,DC=com

ERROR: The specified object value is not valid

It doesnt matter if I make the string uppercase, lowercase, a combination of both, some of the string, none of the string. The same error happens.

Any ideas as what I am doing wrong?
