Mupdate server: no mechanism avaible

[Jérôme NENERT]

Hello,

It seems that my mupdate server doesn't offer any mechanism :

server# mupdatetest -u admin -a admin -w *** -m plain -v localhost
S: * AUTH
S: * OK MUPDATE "server" "Cyrus Murder" "v2.1.18-IPv6-Debian-2.1.18-1" 
"(master)"
Authentication failed. no mechanism available
Security strength factor: 0

Nothing after AUTH !!!!

I use saslauthd with ldap backends. A testsaslauthd works fine.

extract of imapd.conf

sasl_pwcheck_method: saslauthd
sasl_mech_list: PLAIN

Any ideas ?
