[squid-users] Squid Problem Authentication DIGEST

Greetings!

I try to authenticate using digest_ldap, and I get this error on
/var/log/squid3/cache.log:

2008/07/07 09:25:36| helperHandleRead: unexpected read from
digestauthenticator #1, 32 bytes '6e0856007bdf46e7c908985ea25f0000'
2008/07/07 09:25:36| helperHandleRead: unexpected read from
digestauthenticator #1, 1 bytes '
*user filter 'uid=user1', searchbase
'ou=SOMETHING,ou=USERS,o=SOMEDOMAIN,dc=com'*

But i've store on the attribute ldap REALM+':'+MD5, that is something
like REALM:`echo -n "user1:$REALM:password" |md5sum |cut -f1 -d ' '`
e.g:
*l*: REALM:c185b844502d7f00d3a1175a23900cd3

Where 'l' is the ldap attribute, so Can anybody know what's going on in
my squid3?.

Any help, i'll be grateful

PD: When i cancel the authentication on the browser i get this on the logs:

REAL2008/07/07 09:43:58| AuthConfig::CreateAuthUser: Unsupported or
unconfigured/inactive proxy-auth scheme, 'Basic ZWRvcnRlZ2E6amlTaGEzc2Vp'
