## Full access control

LL::NG is a web single-sign-on system, but unlike some systems it can manage rights on applications based on regular expressions on URL.

## Easy to customize

LL::NG is designed using Model–View–Controller software architecture, so you just have to change HTML/CSS files to custom portal.

## Easy to integrate

Integrating applications in LL::NG is easy since its dialog with applications is based on customizable HTTP headers.

### Unifying authentications (federation)

LL::NG can easy talk to other authentication systems using SAML, OpenID, CAS. it may be the backbone of a heterogeneous architecture. Its SOAP API can also be used to dialog directly with your custom applications.

## Sessions

### Session explorer

LL::NG Manager has a session explorer module that can be used to browse opened sessions:

- by users
- by IP
- by date
- by double IP (sessions opened by the same user from multiple computers)

It can be used to delete a session

### Session restrictions

By default, a user can open several sessions. LL::NG can restrict this:

- Allow only one session per user
- Allow only one IP address per user
- Allow only one session per IP address

Those capabilities can be used simultaneously or separately.
