Thanks that works with 1.2

Unfortunately we are prevented from telling you about the specific device
because of a very strict NDA.
It is an NDA from a very litigious systems supplier from silicon valley, so we
must be careful.
All I can say is that its a embedded system that has plenty of clients.
Access to some of the stored data is via an IVR style audio interface, access
to which is controlled via a PIN code.
So think of this as the PIN code you need to enter if you were accessing your
telephone banking service via an IVR.
The embedded client needs to be able to change this PIN code via IMAP.
As a result of a suggestion from Pascal late last week I spent today loading
2.0.rc3 and converting the plugin to the "new form".
What a nightmare.
Is there an easy way to have a plugin included in the configuration and built
as part of the make and make install?
Everything has changed. I was previously happily generating a .so and putting
it the right directory.
I know this is the wrong way to do it, but I was doing something like this.
#
# Build the XCHANGEPASSWORD custom IMAP command
#
export DOVECOT=../../../../dovecot-2.0.rc3
gcc -fPIC -g -shared -Wall \
-I$DOVECOT -I$DOVECOT/src/imap -I$DOVECOT/src/lib -I$DOVECOT/src/lib-auth
-I$DOVECOT/src/lib-charset \
-I$DOVECOT/src/lib-dict -I$DOVECOT/src/lib-dns -I$DOVECOT/src/lib-dovecot
-I$DOVECOT/src/lib-imap \
-I$DOVECOT/src/lib-index -I$DOVECOT/src/lib-lda -I$DOVECOT/src/lib-mail
-I$DOVECOT/src/lib-master \
-I$DOVECOT/src/lib-ntlm -I$DOVECOT/src/lib-otp -I$DOVECOT/src/lib-settings
-I$DOVECOT/src/lib-sql \
-I$DOVECOT/src/lib-storage -DHAVE_CONFIG_H \
change_passwd_plugin.c -o change_passwd_plugin.so
I'm trying to figure out how to build it under 2.0. The documentation assumes a
degree of prior knowledge which I have not
been able to find.
I have built a test framework change_passwd_plugin.c which is 165 lines of C,
its tiny.
Once I get the custom IMAP command been parsed I can then add support in to
store the PIN data in a postgresql database table.
I was hoping to avoid having to learn too much about all this but it seems it
can't be avoided.
Any suggestions would be greatly appreciated.

John
