[Freeipa-users] custom attributes as a part of default ipa permissions

[Petr Fišer]

Hello,
We are currently deploying FreeIPA and we make use of custom attributes.
We defined them in custom.py script (located in 
/usr/lib/python2.7/site-packages/ipaserver/plugins/custom.py). custom.py 
looks like this:

from ipaserver.plugins.user import user
from ipalib.parameters import Int
from ipalib.parameters import Str
from ipalib import _
user.user.takes_params = user.user.takes_params + (
     Str('mailroutingaddress?',
     cli_name='mailroutingaddress'
     label=_('Mail routing address'),)
)

This works fine, server makes the attribute visible through API and also 
the "ipa" command can work with it. Basically, we made those attributes 
part of our default.
However, users (ordinary user in FreeIPA and also sysaccounts) cannot 
access those attributes when binding directly to the LDAP. This is due 
to ACI that FreeIPA writes into the LDAP.

I know that in FreeIPA:

  * For user himself, ldap://self filter can be defined with "ipa
    selfservice-add 'some name' --attrs=mailroutingaddress
    --permissions=read" .
  * For user to read attributes of other users, I can define permission,
    privilege and role and add this role to a user or group.
  * For sysaccounts, it is advised to define custom ACI in the LDAP itself.

What I am thinking of: Is there any way that I can make FreeIPA 
re-generate its LDAP ACI based on our extended user class? Say let the 
IPA server load our custom.py which extends "user" with 
"mailroutingaddress" attribute and then call "ipa whatever" which 
effectively modifies FreeIPA's notion of user class and redefines the ACI?

Kind regards,
