Comment 1 for bug 1677781

We were recently hit by bug #1956833, where GSS-SPNEGO was suddenly disabled and nobody noticed until an app tried to use it.

For that case, I'm thinking about a very simple test that would be like this:

for algo in $ALGORITHMS; do
  saslpluginviewer -m $algo > /dev/null || {
    echo "Algorithm $algo not available"
    exit 1
  }
done

And ALGORITHMS is a list of the algorithms we expect to always be available, like:
  SCRAM-SHA-1 SCRAM-SHA-256 GS2-IAKERB GS2-KRB5 GSS-SPNEGO GSSAPI DIGEST-MD5 EXTERNAL CRAM-MD5 NTLM PLAIN LOGIN ANONYMOUS
