Hi,
I'm trying to get pg_ident to map "user1" and "user1@xxxxxxxxxxxx" to
"user1" in postgres, or vice versa. I'm not picky about which way works.
Kerberos authentication works. I've gotten "user1" to login successfully
with a Kerberos ticket, but I'm not able to get "user1@xxxxxxxxxxxx" to
match.
Environment:
* PostgreSQL 9.6 from PostgreSQL repos
* CentOS 7
* FreeIPA for Kerberos, LDAP, etc.
* Realm A.DOMAIN.TLD
* "user1" database exists
* "user1" role exists
* Logging into CentOS usernames are configured to drop the domain, so
they appear as "user1" rather then "user1@xxxxxxxxxxxx".
pg_hba.conf:
local all postgres peer
host all all 127.0.0.1/32 md5
host all all ::1/128 md5
host all all 192.168.1.0/24 gss
include_realm=1 map=testnet krb_realm=A.DOMAIN.TLD #This is on one line.
Thunderbird is truncating lines.
pg_ident.conf:
testnet /^([0-9A-Za-z_-]+)@A\.DOMAIN\.TLD$ \1
testnet /^([0-9A-Za-z_-]+)$ \1
Regex that works for both in regexr.com:
/^([0-9A-Za-z-_]+)(@A\.DOMAIN\.TLD)?$/gm
Command and lines from pg_log:
$ psql -h db0 # Logged in as user1 with Kerberos ticket
< 2017-09-09 19:50:49.376 CDT - 192.168.1.201 [unknown] > LOG:

Is this something that is possible, or is it something where I need to
pick one way to do it?
Thanks in advance,
Ryan
