So on one of the products we was doing a beta in our live environment, and the upgrade was long but we got their. Come this morning we had 2 problems
The company had stopped supporting Windows 2000 for the software
But the 2nd was very odd, some user could not log in and I was thinking this problem might start to effect others.. After running around pulling people at the Vendor from all around the world we start to see what the problem was.
The e.g. user had the problem no matter what desktop they tried. E.g. user names
Xyeda.Xassan; Xusso.Xouros; Xelal.Xehmet; Xehmet.Xacet; Xonika.Xrasa; Xerdar.Xltun
We finally worked out if the user account was 12 Character only then they could not log in. More or Less then 12 is fine.. only 12 would not let them log in… a few hours later we have a fix.
What this really comes down to is badly written code and design. Where in the back end their might be logic for less then 12 and more then 12 (some one back in v1 of product had limit of the length of user name)
Fun time with Beta software
