SimplePasswordAuthenticator

public SimplePasswordAuthenticator(Properties usersFile,
                           Properties groupFile)

This creates a new authenticator which reads users from the given file usersFile. The group information is read from groupFile. The user file is expected to have one line of the format

     user=password
 

for each user. The password is supposed to be in plaintext. The group file is supposed to have a line for each group, i.e.

     group1=user1,user2,user3
 

Similar to the standard unix password/group format.

Parameters:

usersFile -

groupFile -

Throws:

IOException

                           Properties groupFile,
                           MessageDigest messageDigest)

This creates a new authenticator in the same manner as the above constructor does. It additionally allows for the specification of a message digest algorithm, which is used to compute a digest of the password before comparing it during authentication.

Parameters:
