Re: Determine NT User from E-mail address
Hi Andy,
Thx. for the time you took to answer.
The problem is that there could be several e-mail addresses associated with
an user or group and I need to determine the user or group based on that
address. And I can not assume that the SMTP name is the same as UPN.
I was thinking to do a search on the user and group classes and get all the
e-mail addresses stored in proxyAddresses attribute (this is where I believe
exchange stores all the addresses). Then I'll use this data a cached lookup
table.
Like I've mentioned before - my problem is : given an e-mail - return the
user (or group) that owns that address (if any).

Re: Determine NT User from E-mail address
If you just do a search (use ldifde to test) with a restriction of
"proxyAddresses = smtp:foo@bar.com" and a prop list of "dn" then you should
get your result regardless of whether it's primary or secondary or group or
user.
