Keycloak, LDAP and OIDC: designing enterprise identity correctly

An original source-backed IROSG IT guide.

Keycloak, LDAP and OIDC: designing enterprise identity correctly

Scope

This original IROSG guide covers SSO سازمانی با Keycloak، OIDC و federation using the cited primary documentation.

Core model

در OIDC، application معمولاً credential اصلی کاربر را نمی‌گیرد؛ به Identity Provider اعتماد می‌کند و token را با issuer، audience، signature و زمان اعتبار بررسی می‌کند. LDAP می‌تواند منبع user/group باشد، اما token و session منطق جدا دارند.

Practical workflow

Client type، redirect URI، PKCE، role mapping و token audience را صریح طراحی کنید. JWKS rotation و clock synchronization هم بخشی از availability authentication هستند.

Failure modes

ID Token را به‌جای Access Token برای API نفرستید. wildcard redirect URI و scope بیش از نیاز attack surface را زیاد می‌کند. اتصال LDAP نیز به‌تنهایی authorization مدل application را حل نمی‌کند.

Lab

یک realm آزمایشی با client و LDAP federation بسازید؛ login، logout، role change و token expiry را تست کنید. یک token با audience اشتباه را عمداً به API بدهید و rejection را بررسی کنید.

Production method

Capture a baseline, change one variable at a time, test positive and negative paths, keep evidence, and rehearse rollback before broad rollout.
