<div dir="ltr">Hi<div><br></div><div>We have a Shibboleth IDP which currently talks to one single SP and we are using an out-of-band metadata exchange process.</div><div><br></div><div>We are concerned with the speed of revoking such metadata should something occur with the signing certificate. I am aware that it is possible to have a 3rd party providing signed metadata files however in such a small setup of 1 IDP to 1 SP (At the moment anyway) it feels that setting something like that up won't allow for any gain on the matter as someone will still need to perform the manual revocation of the metadata file on the metadata provider side and also I don't see any added value in terms of security of having such a 3rd party provider compared to an out-of-band solution like we already do.</div>
<div><br></div><div>Am I correct in this? Am I missing something? I understand that something like OCSP check/revocation is not possible with out-of-the-box Shibboleth IDP so how would one tackel the issue of quickly revoking a certificate should something happen?</div>
<div><br></div><div>I am thinking that maybe if the side running the SP would setup such a metadata provider so they can easily and quickly revoke their own metadata supplied to our IDP. If that would be the case, is there any software out there to do this? Could something like ADFS (Being run in SP side) already support this without too much extra effort?</div>
<div><br></div><div>Any input on the matter is welcome.</div></div>
