authorize issue

[hpatel]

Upon executing authorization url in browser:

https://brightkite.com/oauth/authorize?oauth_consumer_key=<ConsumerKey>&oauth_nonce=6de282e429cfbc2cd47410ad509e5038&oauth_signature=4s1xAfv3hs4%2F8WMp4usB75cwkW4%3D&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1285974798&oauth_version=1.0

I get following:

There was an error. The oauth_token you supplied is not valid. You
might need to restart the OAuth process again.

Using: OAuth.php library.

Can anyone point me to right direction.Do I need to supply username
and password.


Thanks,

HP
