Problem : What is the Active Directory field name authOrigBL for ?

I was browsing through my Active Directory using Softerra LDAP Browser (very handy) when I noticed this field assigned to some users: authOrigBL.

I had a look on google but it only found 39 results! (almost a googlewhack)

This is not at all urgent but does anybody know what it’s for?


Solution: What is the Active Directory field name authOrigBL for ?

According to this http://msdn2.microsoft.com/en-us/library/ms978779.aspx  the authOrigBL field is “A backlink to ms-Exch-Auth-Orig Attribute”. (authOrig is the LDAP name for ms-Exch-Auth-Orig)

And by following the given link:  http://msdn2.microsoft.com/en-us/library/ms978778.aspx  the authOrigBL field is then defined as “The users who are allowed to send mail to this recipient”.

So in answer to the question “What is the Active Directory field name authOrigBL for ?”, It provides a reverse lookup to an object that is allowed to send a mail message to the object in question.
Does that sound right?
