Last updated on SEPTEMBER 10, 2017

Oracle Agile Engineering Data Management - Version 6.1.3.0 and later
Information in this document applies to any platform.

Symptoms

Find that if a user uses Kerberos Single Sign On and his user name is entered like DOMAIN/username in field T_USERMAP.C_NAME Windows nevertheless offers the username in different writing sometimes (for example: DOMAIN/USERNAME or DOMAIN/Username).

Expected Behavior:
============
The mapping in the database should be case insensitive as Windows does not take letter case into account.

The issue can be reproduced at will with the following steps:
====================================
1. Create a user in Oracle Agile e6 and map it to a Windows operating system domain user with DOMAIN/username
2. Login with this user to a new machine where he never logged in before as DOMAIN/USERNAME
3. Try to start Oracle Agile e6 with this user
=> Access denied as user name DOMAIN/USERNAME is unknown
4. Log off and log on again with user name DOMAIN/username
5. Try to log in to Oracle Agile e6 again
=> Now access is granted and user can log in to Oracle Agile e6 as user name and mapping matches exactly

Business Impact:
==========
The issue has the following business impact:
Due to this issue, users cannot log in to Oracle Agile e6 when they have not taken letter case into account while log in into the Windows operating system.
