Is it possible to use identityserver 4.0 with PASOE to set up oAuth2 securtity token.? Spring security has the possibillity but can it be incorperated with PASOE??
Yes, you would use IdentityServer 4.0 to create your own oAuth2 Authorization Server.
From 11.7.3 on wards, we support oAuth2 with PASOE, it will convert the oAuth2 token into a client-principal object for you. (Spring Security is included in PASOE).
You can find examples of how to use PASOE and oAuth2 here:
