Hi @all, I struggle with the ACLs, I whant a special account to check the username and PW of the entries on the LDAP-server. Therefore I’ve written the following in the slapd.conf file: access to attrs=userPassword by dn="cn=authenticate,dc=vfk,dc=ldap,dc=com" write by self write by anonymous none

access to * by * write by anonymous none But I can’t authenticate to the LDAP server, does somebody know why?

Greetings John

Better use privileges. I've compiled some of my usual simple patterns into this example config: https://build.opensuse.org/package/view_file/home:stroeder:branches:netwo... YMMV. So everybody caring for real access control should really dive into slapd.access(5) [1]. [1] http://www.openldap.org/software/man.cgi?query=slapd.access Ciao, Michael.
