[Dovecot] pam_authenticate() failed:

[Michael Peters]

Obviously I have an account. This is Solaris 10. I have been tinkering 
with the /etc/pam.conf without success. Does anyone have a solution?

I have this currently in the pam.conf.
dovecot auth    required        pam_passwd_auth.so.1    try_first_pass
dovecot account required        pam_unix_account.so.1

I have tried:
dovecot auth    required        pam_unix_account.so.1  nullok
dovecot account required        pam_unix_account.so.1

And this:
dovecot        auth    required        pam_unix_auth.so.1       nullok
dovecot account required        pam_unix_account.so.1

When trying an IMAP attempt at the command line, this is the log extract.
