Inter-squid authorization problems

I run two squid caches (Sun Ultra 1s, Solaris 2.5, squid 1.1.18) which
require all users to authenticate, i.e. squid is compiled with
USE_PROXY_AUTH defined and a suitable password file (some 22,000 entries)
is configured in squid.conf. That all works fine.

The problems start when I configure each to use the other as a neighbour
and to treat the servers as a cluster. When an object could be supplied
by the 'other' server the transaction nonetheless fails with the message
'Proxy authorization failed. Retry?' displayed by the client browser. It
would seem that the second server is requiring authorization as though the
request were coming direct from the end user rather than a querying
server. It makes no difference whether the two servers are siblings or
whether one is defined as a parent of the other. There are no examples of
the ignore-domain argument to the proxy_auth option in squid.conf but I
assume that this is not intended to prevent the behaviour I am
experiencing (which I assume is unintentional and unforeseen).

Can anybody comment or offer any further insight into the problem, please?

regards,

Adrian Bassett
