RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Ondrej Valousek 2013-01-02 12:50:20 UTC 
Description of problem:
When using sssd to serve maps for automounter it sometimes happen that certain maps are not 'seen'. I observe this behavior with large maps (~100 keys):
[root@logind yum.repos.d]# automount -m | grep 'orlaj'
[root@logind yum.repos.d]# automount -m | grep 'orlaj'
[root@logind yum.repos.d]# automount -m | grep 'orlaj'
  orlaj | belfast:/vol/users/users/&

But the requested key is in the cache:

[root@logind yum.repos.d]# ldb3search -H /var/lib/sss/db/cache_default.ldb -b cn=autofsmaps,cn=custom,cn=default,cn=sysdb | grep orl
no symbol `init_samba_module' found in /usr/lib64/ldb/memberof.so: /usr/lib64/ldb/memberof.so: undefined symbol: init_samba_module
WARNING: Module [memberof] not found
asq: Unable to register control with rootdse!
dn: name=orlajbelfast:/vol/users/users/&,name=auto.home,cn=autofsmaps,cn=custom,cn=default,cn=sysdb
automountKey: orlaj
name: orlajbelfast:/vol/users/users/&
distinguishedName: name=orlajbelfast:/vol/users/users/&,name=auto.home,cn=auto

Version-Release number of selected component (if applicable):
sssd-1.9.2-6.upstream_1_9_3.el6_3.x86_64

How reproducible:
run 'automount -m' command a couple of times and look for missing keys.
Quite easily reproducible.

Steps to Reproduce:
1. configure sssd&autofs to serve maps for automounter
2. run 'automount -m' a couple of times
3.
  
Actual results:
output of the command 'automount -m' is not consistent

Expected results:
'automount -m' should always return the same result
Comment 2 Jakub Hrozek 2013-01-03 10:06:21 UTC 
Pavel will try to reproduce locally.

Comment 4 Pavel Březina 2013-01-07 10:48:41 UTC 
Hi,
I was unable to reproduce it so far. Can you provider logs please? Thank you.
Comment 5 Ondrej Valousek 2013-01-07 12:42:45 UTC 
Logs provided privately by mail.
Comment 6 Pavel Březina 2013-01-11 09:22:42 UTC 
Hi,
unfortunately, the domain log didn't contain anything interesting. Number of returned values is consistent here and everything seems to work as expected. It looks more like a responder problem. Can you provide also sssd_autofs.log please? Thank you.
Comment 7 Ondrej Valousek 2013-01-11 10:02:48 UTC 
Hello,
File sssd_autofs.log is empty.
Comment 8 Pavel Březina 2013-01-11 10:48:38 UTC 
Would it be possible for you to enable debugging for autofs service?

[autofs]
debug_level = level

The best level for us would be 0xfff0.

Attached the log file as requested. Nothing really interesting in there, but I was still able to replicate the issue.
