Question:

What is the definition of the sctool command and some of its options?

Answer:

Most frequently used options:
 

sctool -s	To see the current [s]tatus of sctool (Whether smart card support is enabled or not).
sctool -e	To [e]nable smart card support
sctool -D	This command [D]umps out all the certificates present on the smart card along and whether their attributes match up against AD
sctool -k	To get a new kerberos ticket similar to [k]init

For further detail on these options, see the sctool help by running:

  man sctool

Additional commands:

  sudo rm -rf /var/db/TokenCache/tokens/*

(Clears the smart card token cache of previously inserted smartcards.)


  sudo sctool -r -t ocsp:none -t crl:best -p crl  

(Disable the OCSP check and set CRL to "Best Attempt".)


  sudo sctool -r -t ocsp:none -t crl:none   

(Disables both OCSP and CRL checking.)
