More specifics would help. How did it not work as expected? What is the

The idea is that this is granted to all authenticated users EXCEPT those
in the, in your case, iam-managed-users and admins groups.
We did not user RBAC much up to now. So it is very likely that I did not
fully grasp the whole concept yet.
What I did was adding users to a group called
cn=iam-managed-users,cn=groups,cn=accounts,dc=linux,dc=mydomain,dc=at
and modifying the target filter to
(&(!(memberOf=cn=iam-managed-users,cn=groups,cn=accounts,dc=linux,dc=mydomain,dc=at))(!(memberOf=cn=admins,cn=groups,cn=accounts,dc=linux,dc=mydomain,dc=at))).
Nothing else. Because I thought the "System: Change User" permission
applies to all IPA users by default. This assumption might probably be
wrong...
It is controlled by 'Self can write own password'
$ ipa selfservice-show 'Self can write own password'
Self-service name: Self can write own password
Permissions: write
Attributes: userpassword, krbprincipalkey, sambalmpassword,
sambantpassword
aci: (targetattr = "userpassword || krbprincipalkey || sambalmpassword
|| sambantpassword")(version 3.0; acl "selfservice:Self can write own
password"; allow (write) userdn="ldap:///self";;)
ipapermtargetfilter:
(&(!(memberOf=cn=iam-managed-users,cn=groups,cn=accounts,dc=ipatest,dc=mydomain,dc=at))(!(memberOf=cn=admins,cn=groups,cn=accounts,dc=ipatest,dc=mydomain,dc=at)))
ipapermissiontype: SYSTEM
ipapermissiontype: V2
ipapermissiontype: MANAGED
aci: (targetattr = "krbpasswordexpiration || krbprincipalkey ||
passwordhistory || sambalmpassword || sambantpassword ||
userpassword")(targetfilter =
"(&(!(memberOf=cn=admins,cn=groups,cn=accounts,dc=ipatest,dc=mydomain,dc=at))(objectclass=posixaccount))")(version
3.0;acl "permission:System: Change User password";allow (write) groupdn
= "ldap:///cn=System: Change User
password,cn=permissions,cn=pbac,dc=ipatest,dc=mydomain,dc=at";)
Modifying the ipapermtargetfilter (manually in LDAP) did not produce the
aci I was expecting. Do I have to modify it by IPA API means (eg. CLI?)
or did I modify the wrong attribute?
Cheers,
Ronald
