Hello all,

I’ve been trying to use the Ruby/PAM library to authenticate users but I  
still couldn’t get it working. It looks like Ruby/PAM is not updated  
(according to the readme file, the last time it was tested, kernel  
version  
was still 2.4 and ruby version was 1.6).

I would like to know if anyone knows how can I validate users passwords,  
which are stored in ldap. The idea was to use PAM, but any suggestions  
are  
welcome.

Further details:  
-\> It will be used on a website (using ruby on rails)  
-\> OS: FreeBSD 6.2 or Gentoo

Thanks!
