Well, of course you have LOCAL (but you don't want that for 50 devices :), RADIUS (which comes standard on for example windows servers: IAS or NPS), SDI (an RSA proprietary), LDAP (but you know that), NT domain (for use with older domains), Kerberos and HTTP form (can only be used for VPN user aythentication).
Have a look at:

please give some more details as ENGLISH is mixed up

1) Kerberos and HTTP form (can only be used for VPN user aythentication)???? is it not recmonded   or at all we can not use it
Ernie BeekExpertCommented:
Not quite, did you have a look at the link I provided? It shows a nice overview.
HTTP form can only be used for VPN user authentication. so that is all you can use it for.
Kerberos can be use for authentication of VPN users, Firewall sessions and Administrators. But not for authorization or accounting.

its clear, thanks

just a layman thought.

as TACACS+ is commercial, and in case of less $, what can be your Second best choice.
Ernie BeekExpertCommented:
I'd say RADIUS. That gives you the most options and that is built in in windows servers: IAS (2003) or NPS (2008). So no need for extra $$ :)
