ERROR: "The required mechanism 'SSO' is not available in mechanisms [ABC_WEB_AUTH] from the HttpAuthenticationFactory."

[Jayalakshmi R]

Hello team,

I am trying to enable SSO by adding below configuration :

#/subsystem=undertow/server=default-server/host=default-host/setting=single-sign-on:add(http-only=true,secure=true)

After which deployments for ear and war are failing with below error :

"{\"WFLYCTL0080: Failed services\" => {\"jboss.deployment.unit.\\\"logs.war\\\".undertow-deployment\" => \"java.lang.RuntimeException: java.lang.IllegalStateException: The required mechanism 'SSO' is not available in mechanisms [ABC_WEB_AUTH] from the HttpAuthenticationFactory.
    Caused by: java.lang.RuntimeException: java.lang.IllegalStateException: The required mechanism 'SSO' is not available in mechanisms [ABC_WEB_AUTH] from the HttpAuthenticationFactory.
    Caused by: java.lang.IllegalStateException: The required mechanism 'SSO' is not available in mechanisms [ABC_WEB_AUTH] from the HttpAuthenticationFactory.\"}}"

Any help in figuring this out would be greatly appreciated!

regards,

Jaya
