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 toActive 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?
From microsoft announcement, it seems the spoofing mainly on the Windows and AD and I didn't see how this will affect Siteminder.

R: No issue reported related to the Microsoft security fix.
If you experience any issue that related to the security fix, please report to CA.
Just joined to thank you for your posting. Although not currently using CA, I was struggling to figure out why users were suddenly unable to authenticate through the domain to a certain folder or in-house website. Removing this patch and the v2 patch resolved the issue.
