ERR_employeeadd {'info': 'modifications require authentication', 'desc': 'Strong(er) authentication required'}

Hello! I have slapd 2.4.39 and python 2.6 I tried to create an user via python when I tried do that with root permission - it's OK. But when I did this with config in slapd.conf "access to * by group.exact="cn=LDAP_admins,ou=Roles,ou=Groups,dc=exadel,dc=com" write"

I have an error " ERR_employeeadd {'info': 'modifications require authentication', 'desc': 'Strong(er) authentication required'} "

I tried to use " l.protocol_version = ldap.VERSION{2,3} " via 389 port My function for adding ldif is : l = ldap.initialize(server) l.simple_bind(username, ldapsrvpassword) def employeeadd(): ldif = modlist.addModlist(attrs) l.add_s(dn,ldif)

Will be very appreciate for any help
