I noticed that i can log into BB server with case-insensitive variations of my username. Logging in with `UserA/` is successful while my profile username is is `usera` Is this intentional? The session (remote) username is the profile username. ---

@izymesdev, Case-sensitivity for usernames is handled by embedded Crowd and whatever the backing authentication system is (typically LDAP, such as ActiveDirectory). Bitbucket Server’s code passes the user-entered username and password through to Crowd unchanged, and authentication is performed. If the backing authentication system is case-insensitive-but-case-preserving, as they often are, then you’ll get case-insensitive authentication. Crowd has a [knowledgebase article on case-sensitivity](https://confluence.atlassian.com/crowd/case-sensitivity-of-usernames-and-groups-181536383.html) that may provide some additional details.
