It does the right thing and I'm able to get the value back via pam_getenv(pamh, PAM_ENV_AUTH_DOMAIN) in my Apache module.
My only concern is that the domain name as returned by sssd is lowercase which does not really match the realm as seen by say mod_auth_kerb or mod_auth_gssapi. But I guess uppercasing the string is up to consumer of that value.
hm, the ticket said domain and not realm and unfortunately there might be cases where the upper-case domain name does not match the realm used for authentication.
I've tried to check the behaviour with ssh and it's even more confusing.
I have IPA-enrolled machine, IPA domain example.test, realm EXAMPLE.TEST. I've tried to isolate the SSSD domain namespace from the rest.
I've changed [domain/example.test] to [domain/xxexample.test] and domains = example.test to domains = xxexample.test in sssd.conf, and I've set use_fully_qualified_names = True. My expectation is that the canonical username of the user will be $USER@xxexample.test. That is true, however when I kinit admin, all the following commands
ssh admin@xxexample.test@client.example.tst id ssh admin@XXEXAMPLE.TEST@client.example.tst id ssh admin@example.test@client.example.tst id ssh admin@EXAMPLE.TEST@client.example.tst id
uid=1939400000(admin@xxexample.test) ...
So it's nice that the canonical fully qualified name uses the SSSD domain (the same which I expect PAM stack to return in PAM_ENV_AUTH_DOMAIN), but: why am I able to authenticate as
admin@example.test@client.example.tst
even if there is no example.test domain defined in sssd.conf anymore?
Most probable because admin@EXAMPLE.TEST is the Kerberos principal of your user. If SSSD cannot find a matching user name and the name contains an '@' it tries to find a Kerberos principal which matches the full given name.
