Hi,

I'm working on an open source project that will manage active directory users. I am looking for feedback from Windows/Active Directory Admins on the formats of usernames they prefer or their organization uses. I want to make sure the software allows admins to use the most popular formats when new users are created. Here is the list I have so far:

 1. <firstname><lastname>
 2. <lastname><firstname>
 3. <lastname><firstinitial>
 4. <lastname><firstinitial><middleinitial>
 5. <firstinitial><lastname>
 6. <firstinitial><middleinitial><lastname>
 7. <firstname><lastinitial>

In addition how do you handle multiple identical names? So if two John Smith's exist do you append a numeric number, or interject a middle initial or name to solve the problem?

Thanks for the feedback
