[Freeipa-users] winsync agreement

[Steven Jones]

=======
"Please explain "std AD"."
=======

under 8.4.2 page 178 the option listed as,

--win-subtree says the default is cn=Users,$SUFFIX.

Which I am told is "standard" AD layout.

I assume the $SUFFIX is staff.vuw.ac.nz in my case with IPA as ods.vuw.ac.nz.  So I want to map  cn=staff,dc=staff,dc=vuw,dc=ac,dc=nz to cn=users??,dc=ods,dc=vuw,dc=ac,dc=nz.

at least I think so.

So I take it I should set, --win-subtree cn=staff,$SUFFIX in the command line to make an agreement?

So for the IPA admin group I dont want to sync the admins, they are not in cn=staff but in cn=staff_admins I want them not to sync but I also dont want them wiped out.

Users are simply a user say steven with no privileges. An admin is admin-steven with more permissions so I have 2 logins and 2 passwords depending on the work, its our security policy.

==========
"But why do you have users with the same userid in AD out of the scope of
the sync agreement with the same userid as an IPA user?"
==========

Probably because I dont have enough knowledge of IPA and even less of AD.

In production or in a test environment?

Please explain "std AD".

Let's say you have in AD
cn=Users,dc=example,dc=com
cn=Adminusers,dc=example,dc=com

and in IPA
cn=users,cn=accounts,dc=example,dc=com

and you set up your winsync agreement as

nsds7WindowsReplicaSubtree: cn=Users,dc=example,dc=com
nsds7DirectoryReplicaSubtree: cn=users,cn=accounts,dc=example,dc=com

That is, you want users in cn=Users,dc=example,dc=com to be in sync with
cn=users,cn=accounts,dc=example,dc=com

IPA uses a flat dit - users are grouped not by hierarchy but by
attributes, as opposed to AD which uses hierarchies for grouping.  So
IPA "flattens" hierarchies when it syncs users from AD to DS.

Let's say you have
cn=jsmith,cn=Adminusers,dc=example,dc=com with samaccountname: jsmith
and
uid=jsmith,cn=Users,dc=example,dc=com

because of the way that winsync works, it will think because the AD
entry and the IPA have the same userid, they should be in sync - but
because cn=jsmith,cn=Adminusers,dc=example,dc=com is outside the scope
of cn=Users,dc=example,dc=com winsync will think that the user has moved
outside the scope of the agreement, and will delete the user.  Obviously
it should not do that by default, hence
https://fedorahosted.org/389/ticket/355

But why do you have users with the same userid in AD out of the scope of
the sync agreement with the same userid as an IPA user?
