LinOTP is a linux based solution for one time password authentication. Below you will find information on LinOTP 1.3. There is also the upcoming version LinOTP 2...
LinOTP 2
LinOTP 1 passed through a complete rewrite and redesign. Thus you are not bound to openldap and freeradius anymore. A flexible module concept allows you to use roughly any userbackend to use any authentication mechanism you like to.
LinOTP support HMAC-OTP based tokens like the Aladdin eTokenNG-OTP, eToken PASS and Safeword Alpine.
The website http://www.linotp.org has more information on this.
LinOTP 1.3
LinOTP is a linux based backend based on freeradius and openldap. It consists basically of the components
- OpenLDAP scheme
- freeRADIUS plugin
- linux administration tool for enrolling and managing OTP Tokens. (The eTokenNG OTP are also enrolled on a linux station)
So there is absolutely no windows software needed anymore.
LinOTP now is available as an opensource Community Edition and a more feature full Enterprise Edition.
LinOTP works with the Aladdin eTokenNG OTP and all other devices supporting the HMAC-SHA1 defined in RFC4226 which might be:
- eToken PASS
- LSE mobileOTP solution for smartphones.
Possible applications can be all services were a RADIUS based authentication is done (see HowTos/Linux_and_OTP), which might be Firewalls, Websites, VPN, pam_radius or Terminal Server authentication using LSE's own RadiusGina.
