Re: netID lengths

["Bristol, Gary L." <gbristol () OU EDU>]

We currently have ours set to 8
The first four letters of the persons last name and then a randomly generated 4 digits.
If a person only has three or two letters in their last name then we use that, but considering the combinations 
available this seemed to be a good solution for us.

Subject: [SECURITY] netID lengths

We’re in the midst of changing the process for assigning new netIDs, and one consideration is the length of usernames 
allowed in various systems. We’ve currently got a maximum length of 8, and given that our plan is to never reuse 
netIDs, that maximum causes challenges to maintaining uniqueness and having reasonable netIDs without embedded 
numerals. We’re considering increasing that to 24 characters.

What maximum length do you have for netIDs?

What is the maximum username length supported in most systems? Some cursory web searches gave me these numbers:
Windows 256
Linux 32
Oracle 30
MySQL 16
SQL Server 128
