Workarounds
CNA: A mitigation can be applied to the sssd.conf file that would make the occurrence of the race condition more difficult: 1. Increase the GPO cache time out editing the following configuration directive in sssd.conf file: a) ad_gpo_cache_timeout = 3600 Ps.: This value (3600) should make the cache time out in one hour but would make GPO updates propagation from AD server to local machines take longer.
