Describe the bug

Moved from https://issues.redhat.com/browse/KEYCLOAK-16711

At REST endpoint, no validation is done for ssoSessionIdleTimeout, ssoSessionMaxLifespan, offlineSessionIdleTimeout, and offlineSessionMaxLifespan.
At Admin console, these settings are regulated in positive values. Negative values and zero are rejected.
REST endpoint should have data validation check because zero and negative values are inappropriate for these settings.

Version

RH-SSO 7.5.0

Expected behavior

consistent validation between API and Admin Console

Actual behavior

no validation is done for ssoSessionIdleTimeout, ssoSessionMaxLifespan, offlineSessionIdleTimeout, and offlineSessionMaxLifespan.

How to Reproduce?

./kcadm.sh update realms/<your-realm> -s ssoSessionIdleTimeout=-100

Anything else?
