Description mreynolds 2014-12-04 16:23:57 UTC
This bug is created as a clone of upstream ticket:

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
