Freeradius Usage

[Jesse Stone]

Would Freeradius be the correct technology for this?

For example,

Currently, for me to allow someone access to my OpenVPN server and Samba I
have to first add them as a standard user with the useradd script.  Then I
have use smbpasswd -e to enable their account for Samba.  If I wanted that
user to also be able to SSH into another server I would have to repeat this
process.  After about 3 users I forgot who has access to what.  This is the
process I want to simply.  I want 1 place/script that prompts for every
app/server that I want to restrict access to:  Samba, SSH, Shell access, X,
ect.  I want this infromation stored in a standard SQL type database though
so I can easilly manipulate users once they've been created on the fly.
Perferrably within 1 table like a provided in my last email for an example
simple user management style.

What do large companies that have many users/linux machines use to handle
user administration?
