Jwt authentication not working or showing in log

[mmillies]

Hi,

I know this is late, but I struggled with getting JWT setup as well and haven’t seen answers to questions like this here.

In your situation, the token you have in the url:
eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJ0b2tlbl90eXBlIjoiYWNjZXNzIiwiZXhwIjoxNjgxMTMyNjkzLCJpYXQiOjE2ODEwNjA2OTMsImp0aSI6ImU5OTc2MjI3N2U2NjRlMjA4NTA2MjUyMGMyZTgyNDcyIiwidXNlcm5hbWUiOiJhbmRyZXdAbWlyc2t5dGVjaC5jb20ifQ.s93pF6XOsEZGA8uYZ8p3_ZemnNkGQCBcxu9Pnhbc4enkLqdhrSnmcl68rHzr7HCDUScyVdDbWb293iGvgnRmxSN4hFztm9USCGPWpmRaRtuFp1VVsjI6PN78sBVTqY0CjuVy1MaFiwuW7op9OiXoDoRtTgLZlx5igS72LJRHSDt-n0mZS_52VoRGkq4k9RTU2DR42FSrS7IigR3MT1nz_TlQ1TTa4BOXsHUsd__j3LeKEtSpfaKzCuYMXe0JPYZHGH2Z16dzc40_p5XC4ZzMHee8nqZTnH8uRUTrTn8J1O5vvYAS_ot4dGUMOU3TlgD4NUhLOUK9IunZfhjTNIiouA

appears to be lacking a sub claim/attribute on it. And the JWT implementation at the moment silently ignores tokens that don’t have the sub claim right now. More details on my response to this person:

I want to enable JWT token in grafana ,so that i don't want to give send username and password to client..When i am trying this it is showing failed to start

Hi, This seems to happen to me when grafana didn’t recognize my passed in JWT as a JWT. More specifically, if you happened to specify the incoming header as Authorization as opposed to some other custom header for passing your JWT and it doesn’t recognize the token as a JWT one. One silent error that really messed with me for a while was that the JWT implementation appears to require the claim sub to exist on your token. But the message alerting you to it appears to never be reached/logged as …

hope this sheds light on this for others that come across this post.

EDIT: so one thing to ensure is the tokens you’re using should have a sub claim on them.
