RE: integrate Postgres Users Authentication with our own LDAP Server

We  want to setup ldap authentication in pg_hba.conf, for Postgresql users(other than  postgres super user).

We are getting issue with special characters by following steps given in postgres documentation. 
It is not accepting any special characters as special characters are mandatory in our use case.

Can you please help us or have you any steps by which we can configure any postgres with LDAP?

LDAP authentication is well documented:
https://www.postgresql.org/docs/current/auth-ldap.html

But I don't think you are on the right track.

"pg_signal_backend" cannot login, it is a role to which you add a login user to give it certain privileges.  So you
don'tneed to authenticate the role.
 

"postgres" is the installation superuser.  If security is important for you, you won't set a password for that user and
youwon't allow remote logins with that user.
 

But for your application users LDAP authentication is a fine thing, and not hard to set up if you know a little bit
aboutLDAP.
