sasl2 support included in rc.42

[Carter Bullard]

Gentle people,
I have gotten sasl2 running for argus and all the ra* programs except
radium(), which I should have by early next week (just a minor  
adjustment
since it is both a client and a server of argus data).

The ./configure support is such that sasl2 support for both argus and  
the
clients are off by default.  To turn it on, for either argus or  
clients is:
     ./configure --with-sasl

There is no sasl1 support in rc.42.

If the directories are not in standard places for cyrus-sasl, then:
    ./configure --with-sasl=/full/path/name/to/sasl/dir

It works for all the mechs that I could test (all on Fedora 6):
    PLAIN, ANONYMOUS, LOGIN - using saslauthd with an argus.conf
                               file in the sasl2 config directory  
that contained:
                                   pwcheck_method: saslauthd
                               and saslauthd running as "saslauthd -a  
shadow"
                               this allowed me to authenticate as a  
user account.

    DIGEST-MD5 - using sasldb, generating a simple account using
                                saslpasswd2.  this allowed me to test  
auth, auth-int,
                                and auth-conf, by setting the  
ARGUS_MIN_SSF to
                                something other than 0, in /etc/ 
argus.conf.
                                ARGUS_MIN_SSF=1 is authentication  
with integrity
                                protection for the argus records, and  
any number
                                greater than 1 is suppose to be the  
key length for
                                confidentiality protection (something  
like that).

Hopefully when I put rc.42 up on the server (friday/mon), you all
can be kind enough to give it a try, without too much criticism.
I can provide detailed instructions on how I got it to run, if you need
them.  Currently I am testing it to make sure it didn't break anything
when you don't use sasl2.

Hope all is most excellent,

Carter
