Bug Description

I dont know it is openldap related:

Operation System: Ubuntu 22.04
Packages:
sssd-ldap 2.6.3-1ubuntu3
libldap-2.5-0:amd64 2.5.11+dfsg-1~exp1ubuntu3
libldap-common 2.5.11+dfsg-1~exp1ubuntu3

I have configured sssd to use LDAPS over HAPROXY. With the latest Debian Version and Ubuntu 20.04 i have no error.

But with Ubuntu 22.04 i randomly cant login. Syslog show this error:

May 12 06:57:55 ingress2 sssd[870590]: sssd_be: ../../../../libraries/libldap/request.c:970: ldap_do_free_request: Assertion `lr->lr_refcnt == 1' failed.

If i configured SSSD to use directly our LDAP Server, its working.

Regards Sebastian

Hello Sebastian,

Thank you for taking the time to make this bug report. The error you are encountering shows up through openldap, so marking the bug under openldap is fine. It may be due to multiple sources attempting to free a request. Does this error show up every time you attempt to log in?

Thanks

Hi Lena,

i found the Problem after some time:

I dont know why but Ubuntu 22.04 needs longer to take the LDAP Request. This is also the answer, why ldap without HAPROXY is working.

Now i have set HAPROXY timeout to 5sec and it is working now. With Ubuntu 20.04 (same configuration) ldap Login with timeout of "1sec" is possible.

Regards
Sebastian

You mentioned it is taking longer to process the request but it is working. So I am setting the priority to Low and I am adding this bug to the server team backlog. It will be looked at once we find some time.
