sssd just 'Aborts' on RHEL5.

[Steve Traylen]

sssd does not want to start for me on RHEL5.

# rpm -q sssd 
sssd-1.5.1-49.el5_8.1

on both RHEL5 and SLC5  results in

# /usr/sbin/sssd -i   -d 8
Aborted

This is both with our sssd.conf which is working fine over on RHEL6 but also for the
default
sssd.conf that comes with the package.

The end of an strace is here:  http://pastie.org/4114307  , if I delete the
'var/lib/sss/db/config.ldb 
file then it is created again before the 'Aborted' happens.

Nothing is logged to syslog or sssd.log.

Any ideas.

Steve.

Could you do the following:

yum install gdb
debuginfo-install sssd
gdb /usr/sbin/sssd

at the gdb console:
run -i   -d 8

When it dies:
bt full

Send all the output of that bt full, please.

Back trace as below... I also now realize when I thought
I was using RHEL earlier I was not , I have yet to confirm this
on RHEL, will try to do so.

Can you please confirm what version of SSSD you are running.  Also, what
version of libldb and libtevent. If it's not RHEL, what platform are you
running on?

Also, please attach /var/log/sssd/sssd.log so we can see how much of
initialization completed.

This is both with our sssd.conf which is working fine over on RHEL6 but also for the

sssd.conf that comes with the package.

The end of an strace is here:  http://pastie.org/4114307  , if I delete the
'var/lib/sss/db/config.ldb
file then it is created again before the 'Aborted' happens.

Nothing is logged to syslog or sssd.log.

Any ideas.


Could you do the following:

yum install gdb
debuginfo-install sssd
gdb /usr/sbin/sssd

at the gdb console:
run -i   -d 8

When it dies:
bt full

Send all the output of that bt full, please.

Back trace as below... I also now realize when I thought
I was using RHEL earlier I was not , I have yet to confirm this
on RHEL, will try to do so.



Can you please confirm what version of SSSD you are running.  Also, what
version of libldb and libtevent. If it's not RHEL, what platform are you
running on?

Sure SLC 5.8 which is meant to binary to compatible :

/var/log/sssd/sssd.log is completely empty, nothing is ever written. True with -d 10
as well.
I've checked there are no AVC entries in the audit.log in case its and selinux thing.

The default sssd.conf just contiains:
[sssd]
config_file_version = 2
services = nss, pam

[nss]

[pam]

but it looks to be irrelevant, starting the service does not update the access time on
sssd.conf.

Well, there's your problem. You haven't configured the SSSD service at
all. You need to set it up properly or else it will not start. SSSD does
not work without a properly-configured domain section.

I would say it's not that obvious:

* The configuration file is never accessed based on the access time. i.e the contents
  of the file is irrelevant, the $( ls -lu /etc/sssd/sssd.conf) time is not changed by
starting sssd.
 
* With the same configuration on a centos box you get the sensible error, "no domain
   is defined ".

It's failing before the configuration file. I'll compare the dependencies on
centos and slc to
try and determine if they are different somehow.

On many modern systems, atime has been turned off because it causes
senseless writes. So this is not a valid metric.

Is that a CentOS 5.8 box? If so, then I'd call this a packaging error on
the Scientific Linux folks side.

Yeah, that's probably your best bet. But I'd really recommend putting a
*valid* sssd.conf in place to rule that out :)

Confirmed, SLC had libtevent linked against the older  libtalloc-compat1. Rebuilding
libtevent and all is good (so far) , will arrange for SLC to be updated.
Thanks.
