Closed: Duplicate None Opened 7 years ago by jhrozek.

https://bugzilla.redhat.com/show_bug.cgi?id=885078 (Red Hat Enterprise Linux 6)

Description of problem:
sssd_nss crashes during enumeration and with ldap_default_bind_dn in sssd.conf

Version-Release number of selected component (if applicable):

How reproducible:
Almost always. The crash is in middle of enumerating 30k users on the ldap

Steps to Reproduce:
1. Setup sssd with the following in domain section:
enumerate = True
debug_level = 0xFFF0
cache_credentials = True
ldap_search_base = dc=example,dc=org
id_provider = ldap
auth_provider = ldap
chpass_provider = ldap
ldap_uri = ldap://ldapserver.example.org
ldap_default_bind_dn = cn=Manager,dc=example,dc=org
ldap_default_authtok = password

2. Observe the domain log. Wait for enumeration to complete.

Actual results:
Enumeration goes on forever. And sssd_nss crashes after sometime. See
attachment for backtrace.

sssd_be cpu usage is about 98%
21727 root      20   0  383m 167m 3572 R 98.1 16.9   1:09.61 sssd_be

Expected results:
Enumeration should complete and sssd_nss should not crash.

Because of the extremely long time the enumeration took, Kaushik actually ended up hitting #1717. He verified that he's no longer seeing the crashes with Simo's patch for #1717 and neither did I. Marking as a duplicate.
