lightopenid

A PHP 5 library for easy openid authentication. Based on https://gitorious.org/lightopenid

This fork adds two important features for real-world deployment:

If LIGHTOPENID_TIMEOUT is defined, then this value (in ms) will be used to timeout the CURL OpenID requests; by default, this is limited to 10 seconds (instead of infinite). This can help in blocking potential Denial of Service attacks.
Adds $this->validate_error which will report any problems when validating an OpenID identity.

To use in your Composer project, specify a repository to override the default:

{
  "require": {
    "soundasleep/lightopenid": "dev-master"
  }
}
