Don’t know if people were still having this problem (of not being able to CAC-sign PDFs after upgrading to 10.11.6) — but I was.  None of the suggestions on Fed-Talk worked (but thanks for the answers).  However…  I did find the answer on this post on one of Adobe’s forums.

The following worked for me with Adobe Acrobat Reader DC (2015.017.20053) and Adobe Acrobat XI (11.0.17)...

	https://forums.adobe.com/thread/2184274

	Specifically post number 16 (from “sillybaku”)

Basically one has to “attach” the PKCS#11 module to one’s signing cert.  (It may or may not work with those using Centrify as the interwebs say that Centrify doesn’t uses PKCS#11.)

BTW, signing has changed a but as now Adobe asks one for ones’ “password” when presented with the CAC signature for validation — that “password” is really one’s CAC pin.
