Thread: [GENERAL] LDAP authentication without OU in ldapbasedn
Good morning all,
I can’t seem to get LDAP Authentication working without an OU in the ldapbasedn. My users are spread across multiple OUs without a common root OU which is why I’m trying to authenticate with just the DC.
With pg_hba.conf like this, I can connect successfully from psql…
local all all ldap ldapserver=192.168.xxx.xxx ldapbasedn="OU=DB_Accounts,DC=acme,DC=local" ldapbinddn="CN=XXXX ,OU=DB_Accounts,DC=acme,DC=local" ldapsearchattribute=sAMAccountName ldapbindpasswd=xxxxxxxxxxxxxxx
But if I remove the OU from the ldapbasedn, like this …
local all all ldap ldapserver=192.168.xxx.xxx ldapbasedn="DC=acme,DC=local" ldapbinddn="CN=XXXX ,OU=DB_Accounts,DC=acme,DC=local" ldapsearchattribute=sAMAccountName ldapbindpasswd=xxxxxxxxxxxxxxx
Then I get:
psql: FATAL: LDAP authentication failed for user "xxxxxxxx"
select VERSION();
version
----------------------------------------------------------------------------------------------------------
PostgreSQL 9.6.2 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-11), 64-bit

psql (PostgreSQL) 9.6.2
Kind Regards,

My users are spread across multiple OUswithout a common root OU which is why I'm trying to authenticate with just the DC. As it looks like you're working in a Microsoft Windows AD environment, I'd strongly suggest you consider using Kerberos/GSS authentication instead of LDAP. With LDAP, the user has to constantly re-type their password and the password is sent to the PostgreSQL server. Neither of these are ideal and both are avoided by simply using Kerberos, which is what AD uses. Authentication using LDAP really shouldn't ever be done in an environment which has Active Directory. Thanks! Stephen

Simple bind mode works nicely. Thank you.

Have you tried using the "simple bind mode" where you specify just the ldapsuffix and the ldapserver?
Cheers,
Jeff
