In the HSS web console I changed the default authentication method to Digest-MD5 and save it, but the saved configuration is not being retained.
For example, if I changed Alice's default authentication method to Digest-MD5 and save, I can see that it changes.
But if I then go to Bob, and change his default authentication method to Digest-MD5, and return to look at Alice's default authentication method, I see that it reverts back to AKAv1.
