LDAP and a multi-purpose server

I need advice regarding a server I would like to configure in my spare time.
The system runs Solaris 9 and is currently only used for one light task. As
it has plenty of storage, memory, and is backed up on a regular basis, I
would like to use it to host email and web content for my group and perhaps
eventually several departments. Configuring Postfix, Apache, some sort of
webmail and SFTP access (and nothing more) would be easy for the first few
users, but I would like something that's more scalable and easier to
maintain long term.

I have not used LDAP, but it looks like it might be very helpful. I am
considering setting up OpenLDAP to handle user information and then write
some scripts for adding, deleting and modifying users to the directory and
to the system. The problem is, I'm not exactly sure where to start or what
obstacles I might run into. Should I use PAM? How does Solaris handle a
large number of users, can it use PAM and LDAP for this? The most busy
system I have ever worked with only had a passwd file of about 40 users, all
manually created and maintained.

I do not want to "reinvent the wheel" with my scripts, but I don't want the
overhead or complexity of some of the preexisting "web hosting" solutions I
have seen. I only need IMAP, POP, webmail, SFTP (via OpenSSH but no logins
enabled for most users), some space for personal HTML documents and Apache
to serve those documents. No other services are needed or desired.

Thank you for helping me with this matter. I am totally new to many of these
areas.
