Increase character limit for LDAP user names or make it configurable

Problem Definition

The LDAP sync will skip syncing users with names longer than 50 characters.

Suggested Solution

Should there be a need to have longer names in certain organizations, this should be allowed.
Alternatively:

• If we want to keep the limit to 50, we could shorten the name to less than 50 and add ... at the end or the middle versus skipping the user altogether.
• We can make the length configurable by the admin who's fully conscious about the risk in the note below.

Note

When users are created, the mention names are auto-generated from the names. Increasing the character limit of the name implies the same for the mention name and this has the potential to impact the performance of the auto-complete feature when users are mentioned in rooms.

Workaround

AD attributes may be concatenated within Hipchat to make the display name shorter. For instance, you can combine the first and last name by entering givenName + " " + sn in the User Display Name Attribute field.
