If you look at a normal Group node, which consists out of the object class posixGroup, you will notice that for the filesystem and \s-1PAM\s0 normally the attribuet memberUid is used to describe the membership. Therefore \&\- in this example \- the \s-1ACL\s0 hierary for CipUX::RABC and the file sytem group membership might member out of sync. If that is what you what: ok, but mostly you would not like ask yourself questions like: Why the user (who is in the \&\s-1POSIX\s0 group student) can access object \s-1XY\s0 on the filesystem but can not access the \s-1CAT\s0 module module teacher? The anser would be of course: He is not in the attribute cipuxAclUserMember. .PP To avoid inconsitency we made the follwoing schema valid for debian now: The effective rights on the filesystem concerning roles (aka groups) and the ACLs CipUX uses are the same, because the attribute is the same. .PP .Vb 10 \& Task::cipux_task_list_teacher_accounts | task \e \& | | | ou=Task \& \`\-\- cipuxMemberPid | attribute | \& = teacher.cgi | program name / \e \& | | | ou=CAT \& \`\-\- cipuxMemberRid | attribute | \& = teacher | role name \e / \& | | | \& \`\-\- memberUid | attribute | ou=Group \& = chkuelker | user name / .Ve .PP As you can see memberUid is not a \s-1LDAP\s0 attribute out of the cipux.schema. The second thing is that we dropped the Acl part of the attribute, to state that this might not used only for \s-1ACL\s0. .PP .Vb 10 \& # +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ \& # | RBAC hierarchy structure | \& # +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ \& # \& # dim 0 = etc config space ($config_hr0 ...$config_hr2) \& # dim 1 = distribution space (debian, debian\-edu, ....) \& # dim 2 = RBAC scope (task, cat, ...) \& # dim 3 = RBAC level, hierarchy level (0,1, ..., n) \& # dim 4 = level config space (list, member, ...) \& # dim 5 = level config values (cipux_task_list_tasks, ...) .Ve .ie n .SS "%rbac_explain" .el .SS "\f(CW%rbac_explain\fP" .IX Subsection "%rbac_explain" \&\s-1TODO\s0
