Chrome AWS SAML Token Expiry Reminder

>>> UPDATE v1.0.12 - Detect console page as success after posting for reauth, to support Shibboleth (thanks walterking) - minor improvements >>> UPDATE v1.0.10 - fixed a stupid bug from previous update which broke re-auth. Sorry. >>> UPDATE v1.0.9 - fixed bug for authentication with no existing role/credentials - added an option to not show notification popup - published to Github (https://github.com/gitlon/CASTER) >>> WHY AWS ADFS Federation (SAML) tokens have a maximum expiry of 1 hour. Until Amazon change this limit, you are forced to re-login every 1 hour to use ADFS credentials for the AWS console and/or APIs. This is annoying. This CASTER extension automates the re-login, as well as providing an indication of the time remaining until the current AWS credentials expire. >>> HOW - look at cookies from the AWS Console websites - parse out the current user, role and expiry time - when nearly expired, try to post to the specified ADFS URL to regenerate a SAML token - then post again, to the common AWS SAML login page, to select the current AWS role - if successful, the result is another credentialled-login for another 1 hour. This only works if your credentials are saved - ie that you can navigate to your ADFS page and not be prompted for username and password after the first login. >>> YOU (THE USER) MUST DO THIS You MUST enter *your own* organisation's ADFS url, including the AWS role-provider. Eg: - https://YOURADFS.com/adfs/ls/idpinitiatedsignon?loginToRp=urn:amazon:webservices/ You should also review the default options. >>> OPTIONS - Attempt re-authentication as the current user/role? - Show a Chrome notification before credentials are nearly expired? - The URL for your organisation's ADFS endpoint - When (minutes before) to change the icon time text to yellow - When to change the icon time text to red - When to show the Chrome notification - When to attempt to re-authenticate >>> WHY THESE PERMISSIONS CASTER only needs permissions to two websites: your ADFS URL, and the standard AWS SAML role-choice page. Because you set your ADFS URL as an option, this can't be declared as a permission request. Therefore the extensions declares a request for "all websites". (This will be refined in a later version.) >>> OTHER DETAILS - What does CASTER mean? Chrome AWS SAML Token Expiry Reminder. - I don't want you to steal my AWS or company passwords!? CASTER doesn't store any passwords, or collect or send any private data. It gathers from readily-accessible cookies, and reposts using credentials saved by your browser - in the same way that a user would. You can easily review the extension code to confirm that this is the case. - Organization is spelled wrong in this text!?
