How do I Implement SSO functionaltiy in JMIX without using any external SSO service provider

I wish to build a SSO system in JMIX. SO far all thi links i found, point me to the CUBA site. I just want a simple IDP server up and running in JMIX using which I can log into other applications, which may be in different tech-stacks (eg: react).

I know what I am looking for can be easily done using 3rd party SSO service providers, but I was looking for something inside JMIX platform.

Any pointers and help would be amazing.
Thanks in advance.

CUBA has (had) IDP addon

so maybe you can install CUBA, and then install this addon and look into it and see how it was done …
I speculate that it was discontinued due to the resources needed to build and maintain such a module, while there are many existing and proven products already around. Indeed it is no simple thing, and security sensitive.

I would really advise you to reconsider, one more or less container… check this out: https://github.com/keycloak

Kind regards,
