At a customer site the distinguished name of an Active Directory user in the LDAP directory had the following format:
CN=Lastname\, Firstname,OU=OrganizationalUnit 1,OU=OrganizationalUnit 2,DC=acme,DC=com
In my test environment all users I created had the following format
CN=Firstname Lastname,OU=OrganizationalUnit 1,OU=OrganizationalUnit 2,DC=acme,DC=com
which seems to be the default for Active Directory. Therefore I was not able to reproduce several issues.
To change the distinguished name attribute to the format the customer uses you have to do the steps which are described in this MS Knowledge Base article.
