LDAP Configuration

Team,

we are implementing the LDAP authentication and we are able to connect with LDAP and able to authenticate the user with that. However we have 2 type of users, one - corporate users and available of Active Directory and second application user, which is used by different application to connect with database. 

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.
