Dear Expert,<o:p></o:p>
I face an issue probably you may have some solution for my problem.<o:p></o:p>
I work for a big company,<o:p></o:p>
The problem is we are going to use a Cloud application (SaaS) with SSO but <o:p></o:p>
However due to limitations for federated applications we need to fetch the username from AD in upper case. but we have somehow mix username in our AD therefore we face some issue.<o:p></o:p>
The Solution we have in place is following;<o:p></o:p>
1) We need to change all the username in AD to Upper case<o:p></o:p>
2) We need to ask service provider to support none case sensitive username in AD.<o:p></o:p>
Before we choose above two solutions i need your feedback regarding below questions;<o:p></o:p>
My question is what is the Microsoft recommended username? Upper case or small letter or doesn't matter none-case sensitive?<o:p></o:p>
What is most common username for a Big company with 200 000 work force?<o:p></o:p>
What is the future recommended username for Active Directory (AD) with Windows 2008R2 or 2012?<o:p></o:p>
Will AD support E-mail Id as a username in order to login for domain and so on? <o:p></o:p>
E.g Robert.Martin@company.com? <o:p></o:p>
Thanks in Advance<o:p></o:p>
