## LDAP Configuration
|
||||
|
||||
The example settings are based on an OpenLDAP server with groups defined as "cn" of class "groupOfUniqueNames"
|
||||
|
||||
Enable LDAP
|
||||
|
||||
```bash
|
||||
sudo sed -i "s/LDAP_ENABLED = False/LDAP_ENABLED = True/g"" /srv/webvirtcloud/webvirtcloud/settings.py
|
||||
```
|
||||
|
||||
Set the LDAP server name and root DN
|
||||
|
||||
```bash
|
||||
sudo sed -i "s/LDAP_URL = ''/LDAP_URL = 'myldap.server.com'/g"" /srv/webvirtcloud/webvirtcloud/settings.py
|
||||
sudo sed -i "s/LDAP_ROOT_DN = ''/LDAP_ROOT_DN = 'dc=server,dc=com'/g"" /srv/webvirtcloud/webvirtcloud/settings.py
|
||||
```
|
||||
|
||||
Set the user that has browse access to LDAP and its password
|
||||
|
||||
```bash
|
||||
sudo sed -i "s/LDAP_MASTER_DN = ''/LDAP_MASTER_DN = 'cn=admin,ou=users,dc=kendar,dc=org'/g"" /srv/webvirtcloud/webvirtcloud/settings.py
|
||||
sudo sed -i "s/LDAP_MASTER_PW = ''/LDAP_MASTER_PW = 'password'/g"" /srv/webvirtcloud/webvirtcloud/settings.py
|
||||
```
|
||||
|
||||
Set the attribute that will be used to find the username, i usually use the cn
|
||||
|
||||
```bash
|
||||
sudo sed -i "s/LDAP_USER_UID_PREFIX = ''/LDAP_USER_UID_PREFIX = 'cn'/g"" /srv/webvirtcloud/webvirtcloud/settings.py
|
||||
```
|
||||
|
||||
You can now create the filters to retrieve the users for the various group. This will be used during the user creation only
|
||||
|
||||
```bash
|
||||
sudo sed -i "s/LDAP_SEARCH_GROUP_FILTER_ADMINS = ''/LDAP_SEARCH_GROUP_FILTER_ADMINS = 'memberOf=cn=admins,dc=kendar,dc=org'/g"" /srv/webvirtcloud/webvirtcloud/settings.py
|
||||
sudo sed -i "s/LDAP_SEARCH_GROUP_FILTER_STAFF = ''/LDAP_SEARCH_GROUP_FILTER_STAFF = 'memberOf=cn=staff,dc=kendar,dc=org'/g"" /srv/webvirtcloud/webvirtcloud/settings.py
|
||||
sudo sed -i "s/LDAP_SEARCH_GROUP_FILTER_USERS = ''/LDAP_SEARCH_GROUP_FILTER_USERS = 'memberOf=cn=users,dc=kendar,dc=org'/g"" /srv/webvirtcloud/webvirtcloud/settings.py
|
||||
```
|
||||
|
||||
Now when you login with an LDAP user it will be assigned the rights defined. The user will be authenticated then with ldap and authorized through the WebVirtCloud permissions.
|
||||
|
||||
If you'd like to move a user from ldap to WebVirtCloud, just change its password from the UI and (eventually) remove from the group in ldap
