It is possible to use Basic Users with the ISAM OAuth-Auth capabilities. (ISAM Basic users are users that have NOT been imported into the ISAM registry.) Authentication used to be performed by: isAuthenticated = PluginUtils.isValidUsernamePassword(username, password); I've talked about how this is configured here. This authentication mechanism *can* be configured to use Federated Registries, however... Continue Reading →
Sometimes it might be necessary to manage a session lifetime based on business or security factors, and these might need to be specific to an operation in progress. Here are some helpful techniques for managing the timeouts more dynamically: Understanding Session timeout accuracy Before we go into more detail of setting the session timeouts - it's...

When using the REST API to run some commands against an ISAM for Web/Mobile Appliance, I ran into an HTTP error code that wasn't immediately obvious. Status Code: 405 Method Not Allowed There was no issue with the POST Method, but rather the headers that I sent. It's vitally important that you send the "Accept"... Continue Reading →
My colleague has posted an in depth set of articles on IBM DeveloperWorks for Kerberos configuration with ISAM. It covers both Kerberos integration's, being Desktop SSO with Kerberos into ISAM, and junctioning to servers using Kerberos for Junction SSO. The article is available here: https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/W746177d414b9_4c5f_9095_5b8657ff8e9d/page/Information%20and%20Guides%20for%20Kerberos%20SSO
Updated 09/2015: HTTP 505 error solved. See end of article. On a customer site, I encountered BMC Remedy, and had to perform SSO into the Application from ISAM. My initial attempt included trying to use the standard integration we have with Tomcat versions, as detailed here: http://www-01.ibm.com/support/docview.wss?uid=swg24021393 Unfortunately, this didn't work in the time I'd...

When trying to configure an EAI, I encountered the following error whenever it was supposed to be authenticating the user: Server Error Access Manager WebSEAL could not complete your request due to an unexpected error. Diagnostic Information Method: GET URL: <url> Error Code: 0x38cf042f Error Text: Server Error Solution Provide your System Administrator with the... Continue Reading →
In ISAM v8.0.1.2, some fairly significant changes were introduced to the Management of the ISAM appliance networking interfaces. The update removed the concept of separate NICs for Application and Management interfaces and instead bound those concepts to an IP Address. It added support for VLAN tagging on packets, and provides a number of enhancements around... Continue Reading →
When using ISAM in OAuth patterns, there are a number of ways you can do authorization based on OAuth scopes. In general, at last check, there are three main ways of Authorizing OAuth requests based on their scope. (or other attributes associated with the tokens). The mechanisms available are dependent on which OAuth validation mechanism... Continue Reading →
The vast majority of the work in developing this Authorization Rule was developed by my colleague Shane Weeden. Thanks for sharing Shane! Find more of his work here: https://www-304.ibm.com/connections/blogs/sweeden/?lang=en_us This authorization rule extracts the OAuth values of scope from the ISAM credential and applies a TRUE or FALSE authorization result subject to it containing the...

Update 15/05/2015: It would seem that I may have over complicated this, we have a ISAM feature to do this already! 🙂 Apparently since TAM 6.1.1 we can use static management and error page templates per junction, as stated in the following technote: http://www-01.ibm.com/support/docview.wss?uid=swg21587936 So feel free to choose your own adventure! Different people access... Continue Reading →
What is Clickjacking? Clickjacking (User Interface redress attack, UI redress attack, UI redressing) is a malicious technique of tricking a Web user into clicking on something different from what the user perceives they are clicking on, thus potentially revealing confidential information or taking control of their computer while clicking on seemingly innocuous web pages. It... Continue Reading →
Update 5/08/15: In the ISAM 8.0.1.3 Release, we've added a new stanza to the ISAM Reverse Proxy config file. This allows the easy addition of headers to all ISAM responses. [rsp-header-names] # # This stanza is used to define static HTTP headers which will be added # to every HTTP response from the WebSEAL server. ... Continue Reading →
If you have encoded URLs in scripting thats protected by WebSEAL, it won't automatically filter it, unless you configure the encoding. For example: Javascript Link Backslash U hex encoded: var a = document.createElement('a'); var label = "http:u002fu002fsomeserver:8080u002fdemou002fblah"; a.href = label; var linkText = document.createTextNode(label); a.appendChild(linkText); a.title = "my title text"; a.href = label; document.body.appendChild(a); Without...

When I attempted to configured ISAM for Mobile V8.0.1.0 against an old version of TAM - specifically TAM Policy Server v 6.1.1 FP 8 (and an older 6.1.1 - FP4), I ran into some problems. It generated the following error: System Error HPDCF0062E Could not connect to the Security Access Manager policy server. Error code... Continue Reading →
I posted about modifying a HTTP response back in June 2014 here. This month, I had to put together a HTTP transformation rule that would update a Request header. In particular, the Request header was "out of spec" from the HTTP rules for a Content-Type. It simply updated the request header. <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet...
