Oracle Access Manager alternative: migrate to Keycloak
Move sign-in, MFA and federation off Oracle Access Manager and onto open-source Keycloak — application by application, keeping the Oracle components each app is supported with, and without rewriting your applications.
- Phased, app-by-app cut-over
- EBS, PeopleSoft, JDE and Siebel covered
- Apache 2.0 — no per-user licence
Standards & integrations
- SAML 2.0
- OpenID Connect
- Oracle Access Manager
- WebGate
- Trusted headers
- LDAP / Active Directory
Overview
Replacing OAM without breaking the apps behind it
Oracle Access Manager often sits in front of dozens of applications through WebGates, policies and header mappings built up over years. OAM 11g reached the end of Oracle's Extended Support in December 2021, and teams on 12c still carry the cost of running and patching the full OAM stack. A big-bang replacement is where OAM migrations fail. We inventory what OAM actually does for each application, move user sign-in, MFA and federation to Keycloak first, then retire OAM app by app — replacing WebGates with SAML, OIDC or a hardened proxy where the app allows it, and keeping OAM only where an Oracle application still depends on it.
What we deliver
- OAM inventory: application domains, policies, WebGates and header mappings
- Target design per application (SAML, OIDC, proxy or supported Oracle component)
- Keycloak realm with MFA, passkeys and directory federation
- OAM-to-Keycloak SAML federation for the transition period
- Identity-aware proxy with header parity for WebGate-protected apps
- Decommissioning runbook with rollback per application
Capabilities
What Oracle Access Manager Alternative covers
Configured, tested and documented on upstream Keycloak — then handed over or operated by us.
OAM policy inventory
We review OAM application domains, resources, authentication and authorization policies and header mappings, so nothing OAM enforces today is lost in the move.
Keycloak as the identity provider first
Users sign in at Keycloak — with MFA, passkeys and Entra ID, Okta or AD brokering — while OAM is federated to it, so applications keep working during the migration.
WebGate replacement
Apps behind WebGate move to native SAML or OIDC where they support it, or behind an identity-aware proxy that sends the same headers they read today.
Oracle apps on supported paths
EBS moves to the EBS Asserter or keeps OAM with AccessGate, PeopleSoft uses native SAML on PeopleTools 8.63, and JD Edwards keeps the OAM token validation it's documented to use.
Header parity and hardening
Header names and values are reproduced exactly, client-supplied headers are stripped, and applications only accept traffic from the proxy.
Directory continuity
Oracle Internet Directory, Oracle Unified Directory or Active Directory stays the user source and is federated into Keycloak.
Migration map
Where each OAM-protected application lands
Every row is confirmed against the application's documented SSO options for your release before design.
| What OAM protects | Where it moves | Notes |
|---|---|---|
| Oracle E-Business Suite 12.2 | EBS Asserter with an OCI IAM identity domain, or OAM + AccessGate federated to Keycloak | Both are Oracle-documented routes. |
| PeopleSoft on PeopleTools 8.63 | Native SAML 2.0 to Keycloak | Earlier releases use Signon PeopleCode behind a proxy. |
| JD Edwards EnterpriseOne | OAM token validation kept, OAM federated to Keycloak | EnterpriseOne's documented SSO runs through OAM. |
| Siebel CRM 17.0 and later | SAML federation, or Web SSO through a proxy | Hardened trusted-header path where headers are used. |
| WebGate-protected web apps | Identity-aware proxy with header parity | Or native SAML / OIDC where the app supports it. |
| Oracle Internet / Unified Directory | LDAP federation into Keycloak | Stays the user source until you choose to migrate users. |
How it works
From first call to production
Inventory OAM and its applications
We map every application domain, WebGate, policy and header OAM manages, plus the Oracle components each application depends on.
Make Keycloak the identity provider
Keycloak becomes where users sign in, with OAM federated to it over SAML 2.0, so nothing changes for applications yet.
Retire OAM app by app
Applications move off WebGate in batches, each with a test plan and rollback; OAM is decommissioned once nothing depends on it.
Use cases
Where teams put it to work
OAM 11g still in production
Move off a release that is past Oracle's Extended Support without a risky big-bang cut-over.
Cutting Oracle middleware cost
Shrink the OAM footprint to what Oracle applications strictly need, or remove it entirely.
One identity provider for everything
Bring Oracle applications under the same login and MFA as your SaaS and custom applications.
FAQ
Oracle Access Manager Alternative questions, answered
Is Oracle Access Manager end of life?
OAM 11g (11.1.2.x) is: Oracle's Premier Support ended in December 2020 and Extended Support in December 2021. OAM 12c is still supported — check Oracle's Lifetime Support Policy for your exact release when you plan.
What are the alternatives to Oracle Access Manager?
Commercial options include Okta, Microsoft Entra ID and Ping Identity; Keycloak is the open-source option, licensed under Apache 2.0 with no per-user fees. The harder question is how each one reaches Oracle applications that expect OAM — that's the part we design for.
Can we replace OAM without changing our applications?
For most web apps, yes: a proxy in front of the app reproduces the headers WebGate sent, so the app sees the same identity. Oracle applications follow their own supported paths, and some, such as JD Edwards, still rely on OAM for SSO — there we keep a reduced OAM footprint federated to Keycloak.
How does moving to Keycloak compare with moving to Okta or Entra ID?
The migration work is similar — inventory, federation, application cut-over. The differences are ownership and cost: Keycloak runs in your environment under an open-source licence, and it can still broker Entra ID or Okta if your users already sign in there.
How long does an OAM migration take?
It depends on how many applications OAM protects. Making Keycloak the identity provider comes first; retiring WebGates then happens in batches. We give a timeline once the inventory is done.
