You can configure group based security by tweaking the below parameters in `config.py`. Groups membership comes from LDAP.
Setting `LDAP_GROUP_SECURITY` to True enables group-based security. With this enabled only members of the two groups listed below are allowed to login. Members of `LDAP_ADMIN_GROUP` will get the Administrator role and members of `LDAP_USER_GROUP` will get the User role. Sample config below:
```
LDAP_GROUP_SECURITY = True
LDAP_ADMIN_GROUP = 'CN=PowerDNS-Admin Admin,OU=Custom,DC=ivan,DC=local'
LDAP_USER_GROUP = 'CN=PowerDNS-Admin User,OU=Custom,DC=ivan,DC=local'
```
Create database after having proper configs
```
(flask)% ./createdb.py
