Description Jan Pazdziora (Red Hat) 2016-01-12 14:19:56 UTC

Description of problem:

The change from bug 1211589 / ticket https://fedorahosted.org/freeipa/ticket/4768 introduced new option skip_version_check which is documented in man default.conf(5) as

    skip_version_check <boolean>

        Skip client vs. server API version checking. Can lead to errors/strange behavior when newer clients talk to older servers. Use with caution.

It works when used with RHEL 7.2 IPA client enrolled against (say) RHEL 7.1 server but does not work against RHEL 6 server.

Version-Release number of selected component (if applicable):

ipa-admintools-4.2.0-15.el7.x86_64

On server, ipa-server-3.0.0-47.el6.x86_64 is installed.

How reproducible:

Deterministic.

Steps to Reproduce:
1. ipa user-find
2. ipa -e skip_version_check=1 user-find

Actual results:

# ipa user-find
ipa: ERROR: 2.156 client incompatible with 2.49 server at u'https://ipa.example.com/ipa/xml'
# ipa -e skip_version_check=1 user-find
ipa: ERROR: 2.51 client incompatible with 2.49 server at u'https://ipa.example.com/ipa/xml'

Expected results:

# ipa user-find
ipa: ERROR: 2.156 client incompatible with 2.49 server at u'https://ipa.example.com/ipa/xml'
# ipa -e skip_version_check=1 user-find

users listed, no error

Additional info:

Comment 1 Jan Pazdziora (Red Hat) 2016-01-12 14:24:28 UTC

With ipa-server-3.0.0-25.el6.x86_64 from RHEL 6.4 which reports API version 2.46, and when forcing the client version to that value,

   # ipa user-find 

still fails with

   ipa: ERROR: Unknown option: no_members

with no incompatibility error.

With ipa-server-3.0.0-42.el6.x86_64 and ipa-server-3.0.0-47.el6.x86_64, the incompatibility error happens.

Blocking integration of other product, setting high sev/prio.
