Red Hat Bugzilla – Bug 598501
SSSD doesn't follow LDAP referrals when using non-anonymous bind
Last modified: 2015-01-04 18:42:34 EST
+++ This bug was initially created as a clone of Bug #598485 +++
Description of problem:
If SSSD is configured to use non-anonymous bind (a bind DN is specified and an authentication token such as a password is being used), SSSD does not properly follow referrals. It will only attempt to bind anonymously to the referred server.
More information is available at the upstream bug report:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Set up two LDAP servers requiring non-anonymous bind (anonymous bind should fail)
2. Add a referral on the primary LDAP server for a particular entry that will be answered by the secondary LDAP server. (Use a user entry for easiest reproduction)
3. Configure SSSD with id_provider = ldap and ldap_uri pointing at the primary LDAP server.
4. Request the user entry above (use 'getent passwd <username>')
No results found. The logs for the secondary LDAP server will show a failed anonymous bind.
The user should be returned from the secondary LDAP server.
# ldapsearch -x -h sssdldap.redhat.com -p 389 -D "uid=referred_user3,ou=People,dc=example,dc=com" -w Secret123 -b ou=people,dc=example,dc=com
