Changing username with uppercase or lowercase variation results in a new user with different apps

Issue

I maintain OSE users in a Red Hat directory server and the brokers authorize users through the LDAP plugin.

I have defined a user 'demo' in LDAP and set a password.

I can login to the OSE broker using 'demo' and create an app 'app1'.

If I close the browser (logout) and login with 'Demo', 'dEMo', 'demO', etc. I get a fresh console page with no apps. App 'app1' is missing unless I login with 'demo'.

This does not appear to be the expected behavior. I would assume that regardless of case, 'demo', 'Demo', 'dEMo', or 'demO' should be the same account. This is not the case in my environment.

Here is the oo-admin-ctl-usage --list output showing the same user with different case owning different apps:

User: demo
        Gear: 533348123025ba5025000044, UsageType: GEAR_USAGE, Usage: 0.12973888888888888
        Gear: 533348bb3025ba5025000059, UsageType: GEAR_USAGE, Usage: 0.07982527777777777
User: Demo
        Gear: 53334a133025ba502500007b, UsageType: GEAR_USAGE, Usage: 0.01029728832

Is this a bug, misconfiguration, or normal behavior?
