Re: Username length

[Brian Desmond [MVP]]

Hi,

14 is the max for NT4 compatibility. 127 is the AD limit. You can just key
in a long name in the AD Users & Computers dialog...

Brian-
20 characters for the SamAccountName is the max for pre-Windows2000
compatibility. Here's a reference to it:
http://www.microsoft.com/windows2000/techinfo/reskit/en-us/default.asp?url=/windows2000/techinfo/reskit/en-us/distrib/dsbe_ext_vmon.asp

Note however, that ADUC won't let you enter 20 char. You would need to do
this programmatically or through ADSIEdit. So you can only create a user
name with more than 20 char. if you're not in Pre-Windows2000 compatibility
mode.
