So, it looks like we were sending our auth requests to an F5 which was sending the requests to two ADFS 2.0 servers... when they hit server 01, everything was fine... when they hit server 2, they would error out about 30% of the time (hence the infrequency)... we rebooted server 2 and so far all connections to server 2 are succeeding (not erroring out via SAML.. )...
We are monitoring but this appears to be just Windows being Windows. Jonathan On Fri, Sep 17, 2021 at 4:53 PM Lelio Fulgenzi <le...@uoguelph.ca> wrote: > Keep us updated on the outcome.
