/* The following functions implement SASL binds. A new method
sasl_interactive_bind_s(bind_dn, sasl_mechanism) has been introduced.
* The bind_dn argument will be passed to the c library; however,
normally it is not needed and should be an empty string.
* The sasl_mechanism argument is an instance of a class that
implements a callback interface. For convenience, it should be
derived from the sasl class (which lives in the ldap.sasl module).
See the module documentation for more information.
Check your /usr/lib/sasl/ directory for locally installed SASL
auth modules ("mechanisms"), or try
ldapsearch -b "" -s base -LLL -x supportedSASLMechanisms
(perhaps with an additional -h and -p argument for ldap host and
port). The latter will show you which SASL mechanisms are known
to the LDAP server. If you do not want to set up Kerberos, you
can still use SASL binds. Your authentication data should then be
stored in /etc/sasldb (see saslpasswd(8)). If the LDAP server
does not find the sasldb, it wont allow for DIGEST-MD5 and
CRAM-MD5. One important thing to get started with sasldb: you
should first add a dummy user (saslpasswd -c dummy), and this
will give you some strange error messages. Then delete the dummy
user (saslpasswd -d dummy), and now you can start adding users to
your sasldb (again, use the -c switch). Strange, eh?
* The sasl_mechanism object must implement a method, which will be
called by the sasl lib several times. The prototype of the
callback looks like this: callback(id, challenge, prompt,
defresult) has to return a string (or maybe None). The id
argument specifies, which information should be passed back to
the SASL lib (see SASL_CB_xxx in sasl.h)
