Adding permissions for a user should check that the username exactly matches

When adding permissions to LDAP users with capital cases - I was able to add permissions for LDAP user with wrong case, this means when users login the permissions are not assigned.

From BSP-413 -

A test case for this would be:
1) Have a user from LDAP with a mixed case username that Bamboo sees and lists with that case in the user browser (from your example, ASPNET)
2) In a plan, grant that user some special permissions but give it to a differently-cased version of the username (aspnet)
3) Verify that the plan permissions list the user with the differently-cased version you gave it
4) Log out and log in as the LDAP user
5) Verify that you do NOT have the permission you should for that plan
6) Log out and login as admin user, update the plan permissions to match the username as displayed by Bamboo exactly (ASPNET)
7) Log back in as the LDAP user, you should have the permission now
