SVN USER MANAGEMENT README
==========================

First of all, we talk about the following files and folders:

    .htpasswd
    README
    authz
    cpi
    elab-users.py
    old-scripts-backup

** WARNING: **
In this list, there is one hidden files: `.htpasswd`. This file is hidden on
purpose, so ** don't mess with it **.


quick file overview
-------------------

`.htpasswd`: stores the passwords for the users (classical apache htpaswd-file)

`README`: this file

`authz`: defines the access controll list, so who has access to what

`cpi`: folder that holds the svn repository itself

`elab-users.py`: usermanagement script

`old-scripts-backup`: contains the old scripts to add a user for backup reasons


Usermanagement with `elab-users.py`
-----------------------------------

** HINT: ** To run this scipt first change to the directory with
`cd /var/www/svn` and prepend every command with `./`
(e.g. `./elab-users.py --help`).

The script `elab-users.py` provides some options to add and delete users,
show access information from users and their elab journals. If the scprit
is called with the `--help` option, the folowing help message is displayed:

    Usage: elab-users.py [option] name

    shows and manipulates svn access rights

    Options:
      -h, --help        show this help message and exit
      -g, --groupinfo   display users in a group
      -a, --add         add a regular user
      -r, --restricted  add a restricted user
      -m, --move        move a user to alumni
      -p, --password    reset a user password

    to grant a restricted user access to another folder, you have to carefully
    edit the authz file

the following combinations are possible:

* `elab-users.py`: will show a list of all groups and their users
* `elab-users.py UserName`: shows the access rights of the user and their labjournal
* `elab-users.py -g GroupName`: shows a list of all group members
* `elab-users.py -a UserName`: adds a regular user, creates svn folders and sets a random password
* `elab-users.py -a UserName`: adds a restricted user, creates svn folders and sets a random password
* `elab-users.py -m UserName`: moves an existing user to the alumni group, removes his password
* `elab-users.py -p UserName`: resets the password for an existing user to a new random one


Grant read writes to restricted users
-------------------------------------

As noted in the help message of `elab-users.py`, if a restriced user should have
read access to another labjournal, the `authz` file has to be edited manually.
Here are two examples that grant the user 'UrmilShah' read access to
two different lab journals:

    ... snip ...

    [cpi:/AndreasEvers]
    @restricted =
    UrmilShah = r

    ... snip ...

    [cpi:/HolgerFrey]
    @restricted =
    UrmilShah = r
    HolgerFrey = rw

    ... snip ...

This does not apply to regular users, since these have read access to all folders.
