[squid-users] wb_auth seems to fail while contacting winbind

Hello Squid-Users

I'm still trying to setup my Squid with AD-Authentication through
winbind. here is a little snapshot from my config:

auth_param basic program /usr/lib/squid/wb_auth
auth_param basic children 5
auth_param basic realm GRENCHEN
auth_param basic credentialsttl 2 minute
auth_param digest program /usr/lib/squid/wb_auth

acl all src 0.0.0.0/0.0.0.0
acl AuthorizedUsers proxy_auth REQUIRED
http_access allow AuthorizedUsers
http_access deny all

This should be fine, isn't it?
Squid seems to start and after initializing the authentication modules
it crashes, here also a snapshot from my /var/log/squid/cache.log:

2006/08/14 11:57:02| helperOpenServers: Starting 5 'wb_auth' processes

FATAL: The basicauthenticator helpers are crashing too rapidly, need
help!

Does anyone know how to fix/workaround this problem? I know, an
alternative would be to do this with LDAP, but this is not really what I
desire because SSO is really a nice feature from Active Directory!

Thank you all for help!
