It may possibly be related to this, but this is marked as fixed for 4.3:
https://pagure.io/freeipa/issue/5456
I'm on 4.4.0-14.el7.centos.7
A user had their lastname entry added with the wrong case. I attempted to
update it by changing the case, got an error like this:
[Wed Sep 06 17:46:08.010202 2017] [:error] [pid 15253] ipa: INFO:
[jsonserver_session] aclark(a)DEV.REDACTED.NET: user_mod/1(u'pboppe',
sn=u'Boppe', version=u'2.213'): DatabaseError
I changed it to something else entirely, then changed it to the correct
case.
This happened on attributes: "lastname", "fullname",
"displayname",
"initials", "gecos". I didn't test it elsewhere.
Is there a ticket already for this or should I create a new one? I don't
want to create work for the IPA devs :)
Thanks,
Anthony Clark
