This README clarifies PAM (Pluggable Authentication Modules) support in
SqWebMail.

The configure script automatically enables PAM support if it detects
that PAM authentication is available on your system.  Don't be fooled, you
still need to perform some local setup in order to get PAM authentication
working.  Specifically, you will need to define how the PAM module will
authenticate userids and passwords for the "webmail" service.  SqWebMail
merely requests authentications for this service, and it is up to you to
tell your PAM library how it should handle it.

The exact procedure for doing so should be found in your system administration
manual.  For Red Hat Linux, you can simply create a file called
/etc/pam.d/webmail, and initialize it to contain the following directives:

#%PAM-1.0
auth       required     /lib/security/pam_pwdb.so shadow nullok
account    required     /lib/security/pam_pwdb.so

If you install using the source RPM, this will be taken care of automatically.
