Issue Summary

Changing the username attribute in the user directory does not take effect when using Active Directory.

Steps to Reproduce

• Configure the directory to use samAccountName as username attribute and synchronise
• Change the username attribute to mail and synchronise again, the directory sync completes successfully. However, Bitbucket does not update the username value to reflect the mail attribute on the user's page.

Expected Results

Bitbucket should take the new attribute in effect and do the change to the usernames to override the samAccountName to mail in Bitbucket

Actual Results

Bitbucket should apply the new attribute and update the usernames, replacing samAccountName with the mail attribute in Bitbucket.

Workaround

After saving the changes in the user directory, stop the entire Bitbucket cluster and then start it again. A rolling restart does not work.
