end Auth Adapter Ldap in 1.10.6 is not backward compatible

Zend Auth Adapter Ldap in 1.10.6 fails when using the same options ldap.server1.baseDn = "CN=Users,DC=webex,DC=local开发者_StackOverflow中文版" (this is just one option) the exact same option works in the previous 1.5 or 1.6 versions

if i change the above option to ldap.server1.baseDn = "DC=webex,DC=local" then it works but would always return Invalid Credentials even if the case is Identity Not Found

does anyone know why?

Is there an option for scope? Entry, subtree, base perhaps? Subtree of course is what you want in this context.
