How to install WebGate in Oracle Identity Management environment

WebGate

A WebGate is a web-server plug-in for Oracle Access Manager (OAM) that intercepts HTTP requests and forwards them to the Access Server for authentication and authorization. Specifically an OHS WebGate, i.e. Oracle HTTP Server WebGate is a Web server plug-in that intercepts HTTP requests and forwards them to an existing Oracle Access Manager (OAM) instance for authentication and authorization.

Installing WebGate

There are two important steps for installing OHS WebGate, first is configuring the OHS WebGate and then Registering the OHS WebGate with OAM. See below 

Configuring Oracle HTTP Server WebGate

Registering the Oracle HTTP Server 12c WebGate with Oracle Access Manager


Since 12c version, there is no need for installing WebGate separately. If you have installed OHS 12c server then WebGate comes pre-bundled with it. (In prior versions, 11g and 10g one had to first install WebGate binaries.)


For overview of register/manage webgate in 12c, read  For 12c version  - Register and Manage OAM Agents (aka the WebGate)

If you have a new application, first you will need OHS Server/WebGate which protects this application. Next you will register this WebGate with OAM. There are two ways you can register this OHS/webgate in OAM (see below (1) and (2)). WebGate is an agent (a web server plugin for OAM) which will protect access to the application by intercepting all HTTP requests and forward to OAM for authentication/authorization.


Follow all the steps in Chapter 2 of this Oracle guide - Configuring OHS WebGate for OAM.

 

Register WebGate

There are two ways to register the agent (or WebGate) -

(1) one is via the OAM Console (GUI) and the second (2) via rreg tool via command line, see below both links.

 

15.3 Registering an OAM Agent Using the Console

(1) This step is done through OAM GUI console.

 

15.6 Remote Registration Tool, Modes, and Process

(2) As an alternative to using the console for agent registration, you can use the remote registration utility, oamreg, with Oracle-provided templates.

There are two modes of running the rreg tool, one in-band and other out of band mode. If you have admin access to OAM then use the in-band mode for rreg tool (which is convenient).

 

Read note about WebGate here. Refer these two more blogs, here and here, which provide you steps of configuring webgate/application domain for 12c.

 

In case, you are in 11gR2/R3 versions, refer - Installing and Configuring 11g WebGate for OAM (Apache)

VMware fix for Invalid manifest and ova file import failed errors

Image
Recently we got a OVA file for a virtual machine. The vendor instructions were to import the ova file in vmware Workstation, Player for Windows/Linux, Fusion for Mac, and VirtualBox as well.  The instructions were to take the available package and launch the VM with VMware workstation. The package contained  Module.mf, Module.ovf and Module-disk.vmdk and a Module.ova file. The .mf and .ovf file were 2 KB each whereas the vmdk was several gigs. The package also contained a Module.ova file which was several gigs as well. OVF           Open Virtualization Format MF             Manifest file VMDK       Virtual Machine Disk OVA           Open Virtualization Appliance The ovf file is a xml file that contains metadata for the ovf package The mf file contains the SHA1 hash codes of all files in the package The vmdk file is the disk image of the virtual machine,  VMware Workstation or VirtualBox. (vmdk format was originally developed by VMware and is an open format now). All of

SOAPUI - import certificate

Note: SoapUI has two versions, one is open source and second Professional version. The open source can be download here . (confirmed link 12/19/2018). SSL Handshake issue:   There is an Issue in SoapUI version 5.3.0 (and 5.2.0 version) with SSL handshake error. It was resolved by updating below in vmoptions file ( refer here ). However, the error that shows up while trying to load wsdl is "Error loading WSDL" as below The fix is to Enable TLS 1.2 protocol for SOAP/REST calls in SoapUI, by ammending the vmoptions file to add the directive for TLS as (-Dsoapui.https.protocols=TLSv1.2). Refer here . Update: Version 5.5.0 does not have this issue. If you are on 5.3.0 better upgrade to 5.5.0 which is available now (Feb 2019). I had above issue as well as another issue reaching to https endpoint. Upgrade to 5.5.0 resolved issue. Select "Check for updates" under the Help menu and you will get option for upgrade. Select upgrade current version and accept all defaul

Centrally Managed Users (CMU) - New Feature in Oracle Database 18c

Image
Centrally Managed Users (CMU) Centrally Managed Users or CMU is a new feature introduced since Oracle DB 18c which allows simplified database user management through integration with Microsoft Active Directory (AD). Beginning with Oracle Database release 18c, version 18.1 and later supports direct integration with Microsoft Active Directory (AD) using the new centrally managed users capability. CMU allows the Oracle database to perform user authentication and authorization directly against AD. Benefits of CMU With centrally managed users, users accessing the database can be centrally managed to improve an organization's security posture. An enterprise user (a user in Microsoft Active Directory) can be exclusively mapped to a database account, or many enterprise users (in an Microsoft Active Directory group) can be mapped to a shared account in the database. Microsoft Active Directory groups can also be mapped to a database global role, which provides users with additional privilege
