Jean-Baptiste Onofré commented on KARAF-4520:

I think the jaas modules should have a dedicated bundle. Especially, if we 
isolate DigestPasswordLoginModule in a dedicated bundle, we avoid the refresh.

> Add  DigestPasswordLoginModule so PasswordDigest can work with Karaf JAAS

> So far the assumption with JAAS login modules is that the password is to be 
> compared "as is". However per the ws-security spec, the PasswordDigest for 
> UsernameToken is "the concatenation of the nonce plus the creation time plus 
> the password. The nonce is 16 bytes long and is passed along as a base64 
> encoded value. The way this works is that the client creates the password 
> hash using all of this information plus the password". So the PasswordDigest 
> would change per each invocation, so we can't simply store the passwords in a 
> digest form in the properties file.
> The way to make it work, I think we need a DigestPasswordLoginModule which 
> use a customized checkPassword method where can compare the stored password 
> and the digest password from PasswordCallback (we may need take a close look 
> how this part implemented in WSS4J for digest password comparing)
