Summary: Dovecot authenticator fails on Solaris
Product: Exim
Version: 4.66
Platform: Sun
OS/Version: Solaris
Status: NEW
Severity: bug
Priority: high
Component: SMTP Authentication
AssignedTo: ph10@hermes.cam.ac.uk
ReportedBy: steve@earth.ox.ac.uk
QAContact: exim-dev@exim.org


Due to the fprintf() call in auth_dovecot_server() never completing (or indeed
flushing to dovecot-auth) under Solaris, the authentication fails to complete.

If write() is used instead the whole process works. I've included a unified
diff below which fixes the problem.
