Last updated on JULY 26, 2022

Applies to:

Solaris Operating System - Version 11.4 to 11.4 [Release 11.0]
Oracle Solaris on SPARC (64-bit)

Symptoms

 Fix of CVE-2020-25717 in Samba brought an important change, that is removal of the fallback from 'DOMAIN\user' to just 'user'. This means that customers using implicit mapping of domain users to local (UNIX) users of the same name will no longer be able to use this mechanism after updating Samba to version 4.13.14 or higher (Oracle Solaris 11.4 SRU42 or higher).
