I am looking for an alternative to [Softerra's LDAP Administrator](http://www.ldapadministrator.com/), simply for the price is over-budget for a small team to test the LDAP credentials.

So I really appreciate if someone can point me to some other alternatives for a Windows-based environment. We've got our Active Directory setup already, I only need a tool to confirm the access as a proof to customers. Sorry I am not a security guru, I am quite the opposite...

Thanks for any suggestion in advance!
