Fixed In Version: sssd-1.15.2-50.el7_4.8
Doc Type: Bug Fix
Doc Text:
Previously, the list of cache request domains was sometimes freed in the middle of a cache request operation due to the refresh domains request, as they both were using the same list. As a consequence, a segmentation fault sometimes occurred in SSSD. With this update, SSSD uses a copy of the cache request domains' list for each cache request. As a result, SSSD no longer crashes in this case.
