OpenFire Active Directory issue

I have done new install of Openfire 3.9.3 and I’m hung on installation with LDAP for Active Directory.

Base DN: OU=Users,OU=Finance Group,OU=Departments,DC=xxxxxxx,DC=int

I know the problem is the space between Finance and Group but I don’t know how to fix it. I’ve tried single and double quotes… Please help
