@egorhan Must have been blind when I looked at this the first time. Now I see something that makes me wonder.
Search Base DN: ou=administrators,ou=pm_users,dc=parimatch,dc=local
Bind DN: cn=administrator,ou=pm_users,ou=administrator,dc=parimatch,dc=local
The OU pm_users seems to be on different levels of your LDAP tree. That doesn’t make sense to me. Please double and triple check all the settings. Better you copy & paste the settings from some LDAP browser tool instead of typing those in.
