[Dovecot] Only method=PLAIN

[Manuel Fernández Panzuela]

Hello

I need to authenticate dovecot against openldap. OpenLdap's authentication
method requires SHA.
How must I set dovecot ?

####
/etc/dovecot/dovecot-ldap.conf

hosts = ldap-server
dn = cn=administrator,o=admin,o=ldap-server
dnpass = xxxxx

# # # parametros de prueba
default_pass_scheme = SHA
# # # fin parametros de prueba

auth_bind = yes

auth_bind_userdn = cn=%u,o=usuarios,o=ldap-server

ldap_version = 3

base = o=usuarios,o=ldap-server
scope = subtree

user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid

user_filter = (&(objectClass=posixAccount)(uid=%u))

pass_attrs = uid=user,userPassword=password

pass_filter = (&(objectClass=posixAccount)(uid=%u))

#########

/etc/dovecot.conf
protocol imap {
}

protocol pop3 {
}


protocol lda {
postmaster_address = man...@mfernandez.es
}

auth default {
        #mechanisms = plain SHA

        passdb ldap {
        args = /etc/dovecot/dovecot-ldap.conf
        }

        userdb ldap {
        args = /etc/dovecot/dovecot-ldap.conf
        }

        user = root
}

dict {
}

plugin {
}

If I uncomment #mechanisms = plain SHA  Dovecot doesn't start, the error:
dovecot: auth(default): Unknown authentication mechanism 'SHA'


Thank you
