Amogh, can you retest this for 5.6/5.7 and make sure we have test case(s) in place please.
Matt, please take over this needinfo on comment 8, Thx
Josh, Is this how both users appear in IPA? Username: John.Smith E-mail: jsmith Username: Bill.jones E-mail: billjones Matt P.
So in looking at the user records, neither user has a mail attribute. So when trying to authenticate via LDAP, it can't find the requested email attribute for the user, so it fails appropriately. In order for them to use email addresses as logins, each user would need a mail attribute added to their LDAP record.
Please see comments 6 and 7, which indicate this functionality is not yet supported. R&D will have to verify when the IPA change is rolled out.
