Plugin for updating managed permissions.
The permissions are declared in Object plugins in the "managed_permissions"
attribute, which is a dictionary mapping permission names to a "template"
for the updater.
For example, an entry could look like this:
managed_permissions = {
'System: Read Object A': {
'ipapermbindruletype': 'all',
'ipapermright': {'read', 'search', 'compare'},
'ipapermdefaultattr': {'cn', 'description'},
'replaces_global_anonymous_aci': True,
},
}
For permissions not tied to an object plugin, a NONOBJECT_PERMISSIONS
dict of the same format is defined in this module.
The permission name must start with the "System:" prefix.
The template dictionary can have the following keys:
* ipapermtarget, ipapermtargetfilter, ipapermlocation, ipapermright, objectclass
- Directly used as attributes on the permission.
- Replaced when upgrading an existing permission
- If not specified, these default to the defaults of a permission of the
corresponding --type, or, if non_object is specified, or if not on an
object, to general permission defaults .
- ipapermlocation and ipapermtarget must be DNs
- ipapermtargetfilter and objectclass must be iterables of strings
* ipapermbindruletype
- Directly used as attribute on the permission.
- Not replaced when upgrading an existing permission.
* ipapermdefaultattr
- Used as attribute of the permission.
- When upgrading, only new values are added; all old values are kept.
* default_privileges
- Names of privileges to add the permission to
- Only applied on newly created permissions
* replaces_global_anonymous_aci
- If true, any attributes specified (denied) in the legacy global anonymous
read ACI will be added to excluded_attributes of the new permission.
- Has no effect when existing permissions are updated.
* non_object
- If true, no object-specific defaults are used (e.g. for
ipapermtargetfilter, ipapermlocation).
* replaces
- A list of ACIs corresponding to legacy default permissions replaced
by this permission.
* replaces_system
- A list of names of old SYSTEM permissions this replaces.
* fixup_function
- A callable that may modify the template in-place before it is applied.
- Called with the permission name, template dict, and keyword arguments:
- is_new: true if the permission was previously existing
- anonymous_read_aci: the legacy 'Enable Anonymous access' ACI as
an ipalib.aci.ACI object, or None if it does not exist
Extra keyword arguments must be ignored, since this list may grow
in the future.
No other keys are allowed in the template
The plugin also deletes permissions specified in OBSOLETE_PERMISSIONS.

An attribute will be included if the user has it in LDAP but it does
not appear in *any* historic ACI.
It will be excluded if it is in *all* historic ACIs but not in LDAP.
Rationale: When we don't know which version of an ACI the user is
upgrading from, we only consider attributes where all the versions
agree. For other attrs we'll use the default from the new managed perm.
If the ACIs differ in something else than the list of attributes,
raise IncompatibleACIModification. This means manual action is needed
(either delete the old permission or change it to resemble the default
again, then re-run ipa-ldap-updater).
In case there are multiple historic default ACIs, and some of them
are compatible with the current but other ones aren't, we deduce that
the user is upgrading from one of the compatible ones.
The incompatible ones are removed from consideration, both for
