Hi, i'm trying to use LDAP to authenticate Postgres against a Windows AD. On elder versions it succeeded. Now I'm running postgresql-15-150500.8.19.noarch on a SLES 15 SP5 system. I can't start the db server because it doesn't know the respective configuration parameters: Nov 02 20:42:15 geneious postgresql-script[15577]: 2023-11-02 19:42:15.387 GMT [15577] LOG: unrecognized configuration parameter "ldapbinddn" in file "/var/lib/pgsql/data/postgresql.conf" line 106 Nov 02 20:42:15 geneious postgresql-script[15577]: 2023-11-02 19:42:15.387 GMT [15577] LOG: unrecognized configuration parameter "ldapserver" in file "/var/lib/pgsql/data/postgresql.conf" line 108 Nov 02 20:42:15 geneious postgresql-script[15577]: 2023-11-02 19:42:15.387 GMT [15577] LOG: unrecognized configuration parameter "ldapport" in file "/var/lib/pgsql/data/postgresql.conf" line 110 Nov 02 20:42:15 geneious postgresql-script[15577]: 2023-11-02 19:42:15.387 GMT [15577] LOG: unrecognized configuration parameter "ldaptls" in file "/var/lib/pgsql/data/postgresql.conf" line 112 Nov 02 20:42:15 geneious postgresql-script[15577]: 2023-11-02 19:42:15.387 GMT [15577] LOG: unrecognized configuration parameter "ldapbasedn" in file "/var/lib/pgsql/data/postgresql.conf" line 114 Nov 02 20:42:15 geneious postgresql-script[15577]: 2023-11-02 19:42:15.387 GMT [15577] LOG: unrecognized configuration parameter "ldapbindpasswd" in file "/var/lib/pgsql/data/postgresql.conf" line 116 Nov 02 20:42:15 geneious postgresql-script[15577]: 2023-11-02 19:42:15.387 GMT [15577] FATAL: configuration file "/var/lib/pgsql/data/postgresql.conf" contains errors Nov 02 20:42:15 geneious postgresql-script[15575]: pg_ctl: could not start server Nov 02 20:42:15 geneious postgresql-script[15575]: Examine the log output.

Do I need to switch on LDAP in a certain way ? Thanks for any idea.
