Title: #432: CACHE_REQ: Better debugging for email conflicts
mzidek-rh commented:
"""
The problem is with multiple users sharing the same email in LDAP/IPA. The email attribute
from LDAP is stored twice in the local SYSDB database.
Once as the SYSDB_USER_EMAIL and then also lowercased as namealias. The namealias is used
for most searches because emails are not case sensitive. The only case when it is not used
as lowercase is in the 'by_upn' case. I do not know why, but as I said, I do not
plan to change that now.
