Can we change login credentials from username to email address?

[Kevin Paulus]

Jira Server 8.20.13 is set up with a read-only (with local groups) connection to our .corp LDAP.  Currently, users login with their short username and corp account password.    Management has asked that we change from that to using the user's email address with corp account password.

Can that be done without breaking the existing database table links?
If so, how painful will it be?

@Kevin Paulus, 

You should be able to change that by updating the username attribute field of your connector. Rather than something like SAMAccountName, change it to mail or whatever attribute is representing your users email addresses.

This shouldn't break your tables as Jira has the ability to change usernames natively. I would test this in a test environment first though!

Thanks,

Kian

Thank you Kian,
             Do you think adding an identical directory using mail as the username attribute could be run in parallel so the login could be mixed?
