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 mreynolds 2014-12-04 16:23:57 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/47970

When a SASL bind fails, the target DN is not set.  If password policy account lockout is configured, it attempts to update the password retry count on the dn ("") - which is the Root DSE entry, not a user entry.

This also confuses the COS plugin, and it incorrectly triggers a COS cache rebuild after the failed login.

Comment 1 mreynolds 2014-12-04 21:41:07 UTC

Fixed upstream:

Verification steps

[1]  Setup DS
[2]  Enable Account lockout

ldapmodify ...
dn: cn=config
changetype: modify
replace: passwordLockout
passwordLockout: on

[3]  Attempt a SASL BInd (this is expected to fail)

 ldapsearch -h <host> -p <port>  -b "dc=example,dc=com" -v -LLL -Y GSSAPI "uid=*" dn

[4]  Check the root DSE entry for passwordRetryCount:


 ldapsearch -b "" -s base -xLLL passwordRetryCount=* passwordRetryCount

[5]  If the entry is NOT returned, the fix is verified

Comment 3 Amita Sharma 2014-12-26 12:59:48 UTC

[root@dhcp201-126 pwpolicy]# ldapmodify -D "cn=directory manager" -w Secret123 -p 389 -h localhost << EOF
> dn: cn=config
> changetype: modify
> replace: passwordLockout
> passwordLockout: on
> EOF
modifying entry "cn=config"

[root@dhcp201-126 pwpolicy]# ldapsearch -h localhost -p 389  -b "dc=example,dc=com" -v -LLL -Y GSSAPI "uid=*" dn
ldap_initialize( ldap://localhost:389 )
SASL/GSSAPI authentication started
ldap_sasl_interactive_bind_s: Local error (-2)
	additional info: SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure.  Minor code may provide more information (No Kerberos credentials available)
[root@dhcp201-126 pwpolicy]# ldapsearch -b "" -s base -xLLL passwordRetryCount=* passwordRetryCount
[root@dhcp201-126 pwpolicy]# 

Hence VERIFIED
