we are still using courier 0.32 and are currently thinking about
updating to the current version 0.37. From what I see from the docs,
the authentication code has changed quite a bit between these two
versions, and we are using a custom authentication module that helps
with transparently migrating accounts over from our old POP e-mail
Basically, this custom module verifies username/password against the
old system and then proceeds to create the new account "on the fly".
Our custom module does no more than calling a perl script which does
the actual work, so our C module is quite simple, only has very few
lines of code.
I am now trying to adapt that module to the new authentication code.
If I understand correctly, I am expected to change the code in
preauthcustom.c to do what I need. If this the recommended way of
creating a custom auth module? Or is it a better idea t make a copy of
the authcustom, creating an authscript module? How do I adapt the
build process to have the new module automatically built?
Also, the new code asks for a function that simply verifies if the
user account in question exists. Since I am validating against a
background POP3 system, I can't say if an account exists. The only
thing I can do is verifying if a given password belongs to a given
account. If either password or account is wrong, I get the same error
state, so I can't say if this is the wrong password for an existing
account. What is my authpre function to return in this case? Should I
always return "account exists"?
What is the recommended method of getting a single parameter (here:
the path name to the perl script doing the actual work) into the
authentication module? Should I copy some code from authmysql, reading
my own config file, or should I relay on an environment variable
passed in from the init script (probably reading from
Any hints will be appreciated.
