AdminTokenAction: FATAL ERROR: impossible d'obtenir le jeton SSO d'application
J'essayais d'installer Openam 12 war avec l'agent Apache Tomcat configuré de la manière sso.Mais essayé plus de cinquante fois, mais je ne reçois qu'une erreur.
Si je modifie la valeur de propriété ci-dessous en tant que amAdmin à partir de webagent, lors de l'appel de l'application protégée dans la deuxième instance de Tomcat, elle est systématiquement redirigée vers la même page, sans exception. amAdmin est mon utilisateur administrateur de la console openam.

S'il vous plaît, aidez-moi à résoudre ce problème.Merci d'avance.
J'ai eu un problème similaire dans le passé où après que l'utilisateur se connecte à l'aide de la connexion OpenAM, il se redirige vers lui-même.
Le problème était le domaine des cookies. Lorsque OpenAM s'authentifiera, un cookie sera créé avec le jeton de session. Si Tomcat se trouve sur un domaine distinct, il ne pourra pas rechercher le cookie.
Vous voudrez peut-être vérifier votre domaine dans la console OpenAM -> configuration -> système -> plateforme
Mon application était Drupal mais je pense que la configuration de Tomcat est:
<Context sessionCookiePath="/something" sessionCookieDomain=".domain.tld" />
Une solution possible à votre problème pourrait être d’utiliser le com.iplanet.am.naming.map.site.to.server Ce tutoriel devrait couvrir tout ce qui vous concerne :) https://backstage.forgerock.com/#!/docs/openam/12.0.0/ admin-guide
L'un des problèmes que j'ai observé avec ce type d'erreur est que Open AM 13 pourrait ne pas être compatible avec Tomcat-8.5.12. Veuillez modifier l'installation de Tomcat dans laquelle Open AM est déployé vers Tomcat-7.0.69. Cela a résolu mon problème.
