Fixed In Version: sssd-1.15.2-50.el7_4.7
Doc Type: Bug Fix
Doc Text:
Previously, the calls provided by SSSD to send data to the Privilege Attribute Certificate (PAC) responder did not use a mutex or any other means to serialize access to the PAC responder from a single process. When multithreaded applications overran the PAC responder with multiple parallel requests, some threads did not receive a proper reply. Consequently, such threads only resumed work after waiting 5 minutes for a response. This update configures mutex to serialize access to the PAC responder socket for multithreaded applications. As a result, all threads now get a proper and timely reply.
