File_Passwd::staticAuth()

File_Passwd::staticAuth() -- Fast authentication

Synopsis

require_once 'File/Passwd.php';

mixed File_Passwd::staticAuth (string $type, string $file, string $user, string $pass [, mixed $opt = ''])

Static user autentication.

Though this approach should be reasonable fast, it is NOT with APR compatible MD5 encryption used for htpasswd style password files encrypted in MD5.

Generating one MD5 password takes about 0.25 seconds!

Depending on $type, $opt should be:

string $type

Unix, Cvs, Smb, Authbasic or Authdigest

string $file

path to passwd file

string $user

the user to authenticate

string $pass

the plaintext password

mixed $opt

Returns TRUE if authenticated, FALSE if not, or PEAR_Error on failure.

Table 37-1. Possible PEAR_Error values
