<pedant> A/D does not enforce the uniqueness of a UPN (ADU&C does, but that's just a GUI). However, if duplicate UPNs exist in a forest, the accounts associated with those duplicates will be unable to authenticate via a UPN. </pedant> -----Original Message----- From: Mulnick, Al [mailto:Al.Mulnick@xxxxxxxxxx] Sent: Friday, September 17, 2004 5:33 PM To: [ExchangeList] Subject: [exchangelist] RE: users with same cn in an OU http://www.MSExchange.org/ You are correct. As long as the UPN, samaccountname, and RDN are unique, then they can be created. To the system, it's usually a GUID anyway. -----Original Message----- From: Monika Rabarison [mailto:monika.k.rabarison@xxxxxxxxxxxxxxx] Sent: Friday, September 17, 2004 5:28 PM To: [ExchangeList] Subject: [exchangelist] RE: users with same cn in an OU http://www.MSExchange.org/ On Fri, 17 Sep 2004, Mulnick, Al wrote: > http://www.MSExchange.org/ > > Couple of things come to mind. > I prefer to just get rid of the dead weight and only issue accounts to > those that have a unique name; it cuts down on admin overhead. ;) I agree. > > Similar to SMTP addresses in a domain, there can be only one.
