trying to retrieve CA cert via LDAP .... stuck

[Pieter Baele]

Hi,

I've a weird problem with 2 hosts on ipa-client-install registration.
All my servers are using a 99% alike kickstart profile.

8 hosts did their registration almost immediately (after submit of admin)

But on 2 servers I am stuck with:
stderr=
trying to retrieve CA cert via LDAP from ....

Any idea what the reason could be? I checked: DNS, firewall
But all verifications and discovery before this step are successful.

It's only possible I did a ipa-client-uninstall on those hosts before.
(not 100% sure)

Sincerely Pieter

Shouldn't matter unless you are running an ancient version of RHEL 6.x.

I'd start with the 389-ds access log and the KDC log on the IPA master
and see if connections are being made at all, and with what results.

No, only "fresh" and updated RHEL 7.3 hosts.

Connections are being made, but still ipa-client install.
Can't wait forever on a solution of RH Support, they have/had no clue at
all, so I'll reinstall - yet the issue intrigues me a bit.

Ok, you were the one that brought up re-installing...

Y
You haven't provided any information here that would allow us to help.

Yes indeed, I was the one that brought up reinstalling 2 of our hosts.

I have a deadline, so there is no choice. Those are 2 management hosts we
need.
Also I never got a request, "please, this looks intriguing for us at well"
....
I could have reinstalled right away instead of trying to debug the ipa
registration process. But all my other 99% similar hosts registered without
a problem.....
We lost precious time also because I had to explain that the engineer was
looking in the wrong direction. Not something a customer should do (!).

But I am still interested in what happened and in IPA in general, hope
there is nothing wrong with that?

Thats why I also submitted some limited information to the mailinglist.  It
is not the first time a mailinglist or IRC is more direct.... instead of
going to several support people first.

As demanded I provided an strace as well, and it was clear that the
freeipa-client-install was hanging at the point as explained before.

No explanations from logs and traces IMO.
The only thing that was changed on those 2 hosts was the hostname - but
BEFORE the install of the client. Which was also misunderstood by the
way....
