Hello,

I found the following solution to your problem see if this can solve out your issue..

"Unable to Authenticate Resource on Internet Explorer"

Previous releases of Oracle Access Manager supported only Latin-1 encoding. 10g (10.1.4.0.1), however, supports UTF-8 encoding. This problem should no longer occur.

Symptom: You receive Unable to Authenticate Resource errors on Internet Explorer.

Cause: Internet Explorer provides the advanced option to always convert UTF characters in URLs. Oracle Access Manager automatically does this as well. Having both enabled causes authentication errors.

Solution: Complete the steps that follow to remedy "Unable to Authenticate Resource" errors on IE.

To remedy this

1. Open the globalparams.xml file in a text editor. This file is stored in two locations, and both
must be edited:
* \IdentityServer_install_dir\identity\oblix\apps\common\bin\globalparams.xml
* \AccessServer_install_dir\access\oblix\apps\common\bin\globalparams.xml

2. Set the doUtfConversion parameter to NO and save your changes.

Note: If you set this after importing the UTF-8 data, restart the Web server, close all
browsers, and open a new browser window.

3. In Microsoft Internet Explorer, select Internet Options from the Tools menu.
4. In the Internet Options dialog box, select the Advanced tab.
5. Under Browsing, deselect the Always send URLs as UTF-8 check box.
