Then you'd have something like (untested):

Thank you very much for the reply Phil.
Your untested auth_plain works a charm. I've amended my collection
script to not put the :: on the end and authentication now seems to
work. Turns out I'd followed a guide that used md5 passwords and had
an md5 check in the condition which of course wouldn't work seen as
the passwords aren't md5 passwords. All the OS concerned are CentOS 6
built exactly the same so no problems with different routines.
Its late here so I've put it in place on a backup server and will give
it thorough testing tomorrow evening out of hours.
Much appreciated.

Colin.
It turns out that I might have spoken too soon.
After a few hours monitoring it would appear that a number of accounts
will not authenticate but there is no apparent reason.
Example 1: Using the same configuration and the same passwd file on two
servers. My Thunderbird client will not authenticate to server 1 but
will authenticate to server2 using the exact same details
Example 2: Numerous servers use server 1 as a smarthost. One reseller
has all their servers using a similar format of
[email protected] and the password is the same for all the
smarthost accounts. Most work but one or two do no. These all have
exactly the same hash in the passwd file so there is no reason why some
would work and others not.
It does log something:
2011-10-10 07:55:57 login_server authenticator failed for localhost
(my.server.name) [1.1.1.1]: 535 Incorrect authentication data
(set_id="[email protected]")
So the next question I have is how do I debug this and figure out why
some authentications are failing?
Regards,
Colin.
