Hello,

When enrolling a opensuse tumbleweed client, ipa-client-install fails to
get the cacertificate from ldap with error:

ipa server is 4.11.0 (centos stream 9 latest)

ipa client is 4.11.1 (opensuse tumbleweed) from this source:
https://build.opensuse.org/package/show/security%3Aidm/freeipa


With debian 12 and ipa-client 4.9.11 the enrollment succeeds.

With centos stream 9 and ipa-client 4.11.0 the enrollment succeeds.

Is there a limitation with clients newer than the server?
Not usually.

What can I check to fix this issue?
I'd start with comparing what version of python-cryptography is on the
working vs non-working systems.

debian: 38.0.4-3 (python 3.11)

centos stream: 36.0.1-4.el9 (python 3.9)

tumbleweed: python311-cryptography 42.0.5-1.1

Indeed, it is quite newer on tumbleweed.

https://cryptography.io/en/latest/changelog/
There are some deprecations in 39.0 that might be in play but I don't know exactly what is used by ipa.
