we are implementing the LDAP authentication and we are able to connect with LDAP and able to

Below entry i did in the pg_hba.conf file, if i create user in DB (similar exist on AD) it works.

However if i create one user with password, it calls the LDAP server for authentication

and fails as it does not exists in AD.

 

host all all 0.0.0.0/0 ldap ldapserver=<LDAL Server> ldapbasedn="OU=Corporate,DC=etch,dc=com" ldapbinddn="CN=AdSyncAcct,OU=Service Accounts,DC=etch,DC=com"

ldapbindpasswd="Password" ldapsearchattribute="sAMAccountName"

 

we are using the postgres 10.10 version.

 

can you please suggest the pg_hba.conf file entry, that will help us to authenticate the users

from LDAP and from postgres as well.

 

Create a NOLOGIN role "ldapusers" in PostgreSQL and assign the users to authenticate

with LDAP to that group.

 

Then use two lines in pg_hba.conf:

 

host all +ldapusers 0.0.0.0/0 ldap ...

host all all 0.0.0.0/0 scram-sha-256

 

All users in the "ldapusers" group will be authenticated with LDAP,

and the others will "fall through" to the password authentication.

 

Yours,
