sasl_password_format=crypt but no crypt?

[Jacob Friis Larsen]

I have set sasl_password_format=crypt and crypt=1 in /etc/pam.d/imap and 
/etc/pam.d/smtp but I can still login with plain text passwords in the 
database?

Do I need http://frost.ath.cx/software/cyrus-sasl-patches/ for 
Cyrus-imapd 2.1.16-6 (Debian package)?

Thanks,
Jacob
