I've recently been trying to lock down Samba4's default ACLs, in it's generated LDAP backend configuration.
I have memberOf configured to 'error' on dangling links, which I need for Samba.
But I seem to be having some trouble with ACLs. I've attached my full config file, but the key part is:
access to dn.base="" by dn=cn=samba-admin,cn=samba manage by anonymous read by * read
access to dn.subtree="cn=samba" by anonymous auth
access to dn.subtree="${DOMAINDN}" by dn=cn=samba-admin,cn=samba manage by * none
If I change the last line to 'by * read', then the error is returned, but otherwise (due apparently to "" being unable to read the entry to validate it's existence).
Shouldn't the search operations happen as the rootdn or memberof-dn, or am I missing some other configuration element here?
Not sure I got the point, but what I'm sure about is that any check about dangling links is done while writing. The result of search operations is based on what values the link contain, statically. Apart from this, yes, internal ops are performed using the rootdn, in order to skip any issue related to access control.
