Thanks for advices.

I am working on the project which is called AliEn (alien.cern.ch). It is 
aimed at the creation of the Grid computing environment for CERN 
(www.cern.ch) ALICE (aliceinfo.cern.ch) experiment. AliEn users have 
2 ways of authentication: 1. using X509 certificates, 2. using 
SSH keys. Internally AliEn also uses another authentication 
mechanism which is based on string tokens. AliEn is written in Perl and it uses 
SASL for authentication. AliEn developers have extended Authen::SASL 
(www.cpan.org) perl module and developed plugins (to support 
authentication based on X509  certificates, SSH keys and string tokens) 
for it. My task is to create Cyrus SASL plugins for all three mechanisms.
