Dovecot auth-worker error after cram-md5 auth

Default it was: "auth_mechanisms = plain login" and I added cram-md5.
After restart all work perfectly. But after I added:
driver = passwd-file
args = scheme=cram-md5 /etc/dovecot/cram-md5.pwd
I can't set default lines because I got error. Please tell me which lines
should be changed to resolve this issue. Should I remove "login" from
auth_mechanism ("login" was default setting and I would like to move back
to default settings)?
