Login account should be case-insensitive for LDAP

Current Situation
When a user is created in LDAP, the username and password are not case-sensitive. If a user name is smith then it also accessible by user name sMiTh, SmItH, etc. On login to the JOC Cockpit with the username SmItH the login gets successful, but JOC Cockpit get freezed with an exception Access denied

How to reproduce:

• Set up JOC Cockpit with LDAP authentication; users sign in with plain username and password.
• Sign in at least once with "username" in all lowercase characters.
• Make sure a profile entry is created for that account "username" in JOC_CONFIGURATIONS in the reporting database.
• Sign out.
• Sign in again but change one or more characters in your username to uppercase, e.g., "Username" or "usernaME"
• Sign in is successful, but JOC Cockpit is broken all over the place.

Desired Behavior
The JOC Cockpit should be able to handle login for case-insensitive credential.
