Subject: [PATCH 29/29] Bug 1347760 - CVE-2016-4992 389-ds-base: Information
disclosure via repeated use of LDAP ADD operation, etc.
Description: do not overwrite rc used to decide if bind was successful.
When the bind is through ldapi/autobind, an entry does not exist to be
checked with slapi_check_account_lock. In that case, a variable rc is
not supposed to be modified which confuses the following code path.
Reviewed by nhosoi@redhat.com.
