Use /login and /logout URLs instead of SSP
Nova PaaS provides
/logout endpoints that will redirect to SimpleSamlPhp URLs. This library does not use these at this time, as
/logout does not support redirecting to a provided location, but will redirect to the web-root. Therefore, this library predicts the SimpleSamlPhp URL and uses that, as it supports redirection.
A better solution will be to always use
/logout, as the SimpleSamlPhp backend may change in the future. This is an easy change that should be done as soon
/logout supports redirection.
