PostgreSQL 9.3 running on Linux - need to authenticate vs. Windows Active Directory

- Database server is Ubuntu Linux 3.13.0-68-generic - Database is PostgreSQL 9.3.10 - LDAP set up according to https://cdc.iseage.org/tutorial-pam-ldap-authentication-active-directory-debianubuntu/ - pg_hba.conf line: host all all 127.0.0.1/32 ldap ldapserver="my.ldap.net" ldapprefix="uid=" ldapsuffix=",ou=People,o=my.net,dc=my,dc=ldap,dc=net" - There is a PostgreSQL account set up for searched.user@my.net I'm able to get successful LDAP searches: ~>$ ldapsearch -h my.ldap.net -x -b "ou=People,o=my.net" "uid=searched.user@my.net" cn That returns as expected, the CN of the user looked for. I'm also able to bind lookups as in ~>$ ldapsearch -h my.ldap.net -W -D "uid=bind.lookup@my.net" -b "ou=People,o=my.net" "uid=searched.user@my.net" cn and have the correct information returned after the bind.lookup user enters their AD password. When I try: psql -U "searched.user@my.net" I get prompted for the password. Upon entering the password, I get: psql: FATAL: password authentication failed for user "searched.user@my.net" That's what I've tried. Any ideas on how I can get this working? I should mention that it is NOT desired to join the database server to the Windows domain - too many other linkage issues would arise.
