# GRR

## Presentation

GRR is a room booking software.

## HTTP header

### Configuration

GRR has a SSO configuration page in its administration panel.

Do not use Lemonldap mode, which is for a very old Lemonldap version, but HTTP authentication.

Set the default profile of connected users and which headers contains surname, firstname and mail.

GRR will check the username in REMOTE_USER, so use remote header conversion if you are in proxy mode.

### GRR virtual host in LL::NG

Access rules:

- ^/index.php => accept
- default => unprotect

Headers:

- Auth-User $uid
- Auth-Sn: $sn
- Auth-GivenName: $givenName
- Auth-Mail: $mail
