We have been notified of an issue with Microsoft security update MS15-027 which may cause data to be unavailable to SMB clients that authenticate to
Active Directory through the NTLM authentication protocol.
SMB/SMB2/SMB3 clients may experience login failures when authenticating through Microsoft AD and the NT LAN Manager Security Support Provider (NTLMSSP). Authentication failures may affect clients attempting to access data through HTTP-based protocols.
Is CA aware of any issues for users accessing Siteminder sites protected by the Windows Authentication scheme?
