I am currently setting up WHD to function with multiple Active Directory domains, many of which have user accounts with the same login in (jdoe@domain1.org and jdoe@domain2.org for example) which WHD will not allow either to log in because they both have the login of jdoe. To alleviate this issue we'd like to have their login to be their email address, or username@domain. I've located where we can change this value in the LDAP/AD attributes mapping which is currently sAMAccountName. I can see the available options, however there isn't one option that clearly states user's email address. I've searched the forums and done a cursory search on Google.
Thank you, any advice would be appreciated!
