[Freeipa-devel] [PATCH] ipa-pwd-extop: allow password change on all connections with SSF>1

[Sumit Bose]

Hi,

currently the change password plugin does not check if the connection is
coming from a local LDAPI socket and denies password change requests via
LDAPI. This patch changes the check to just look at the overall SSF of
the connection which covers all types of connection.

There is a similar check in ipa_enrollment.c. But I think enrollments via
LDAPI does not make much sense so it does not need to be changed.

This patch should fix https://fedorahosted.org/freeipa/ticket/1877.

bye,
Sumit
