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?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.If this question can be reworded to fit the rules in the help center, please edit the question.

What do you mean by manage? I really don't understand what you are asking here. Can you elaborate? – Zoredache May 10 '10 at 3:06
Yea, its pretty simple, maybe its not clear. When you create new users in active directory today what is the username format you use and why? If the software I have allows you to create new users automatically through simple name input fields obviously you would want it to follow your naming convention. – Brent Pabst May 10 '10 at 5:27
In most of the environments I've managed, usernames were purposefully not related to the user's name to avoid issues with duplicate names, name changes, and all of the other headache involved with name based IDs. – Ryan Bolger May 22 '15 at 16:19

We went a different direction with this question. We ended up building dynamic elements that allow for any combination of the user's name to be used as a username. However the formats above do appear to be the most used.
