Ranger usersync ad username character limit

When usersync syncs from Active directory (LDAP) the user name (sAMAccountName) and group name gets truncated if they are more than 20 characters. The username synced would be incorrect and the users doesn't get applied correctly to policies.

Is there a way to increase the character limit on usernames synced from AD?
