Hi,

Please, I need help with how to configure postgresql to use LDAP for Authentication. 

Here is what I have tried;

host all all 0.0.0.0/0 ldap ldapserver=ldap://adserver.domain.com ldapport=389 ldapprefix="DOMAIN\" ldapsuffix="" ldapbinddn=postgres-user@domain.com ldapbindpasswd=mypassword


host    all             all             0.0.0.0/0         ldap        ldapurl="ldaps://adserver.domain.com:636" ldapbasedn="OU=Users,OU=England 053,OU=Commercial Services,DC=domain,DC=com" ldapbinddn="postgres-user@domain.com" ldapbindpasswd="mypassword" ldapsearchattribute="OU=Users,OU=England 053,OU=Commercial Services,DC=domain,DC=com"



host    all             all             0.0.0.0/0         ldap         ldapserver="adserver.domain.com"     ldapport=636     ldapscheme="ldaps"     ldapbasedn="OU=Users,OU=England 053,OU=Commercial Services,DC=domain,DC=com"     ldapbinddn="OU=Users,OU=England 053,OU=Commercial Services,DC=domain,DC=com"     ldapbindpasswd="mypassword"     ldapsearchattribute="adservice-account"

And this is the error I'm getting;

[postgres@myserver ~]$ psql -U myuser mydatabase
psql: error: connection to server on socket "/run/postgresql/.s.PGSQL.5432" failed: FATAL:  no pg_hba.conf entry for host "[local]", user "myuser", database "mydatabase", no encryption
[postgres@myserver ~]$ psql -U "MYDOMAIN\myuser" mydatabase
psql: error: connection to server on socket "/run/postgresql/.s.PGSQL.5432" failed: FATAL:  no pg_hba.conf entry for host "[local]", user "MYDOMAIN\myuser", database "mydatabase", no encryption

Fix your pg_hba.conf, LDAP is the least of your problems.

Thank you
