Re: [cas-user] Zoom Integration

[Brian T. Huntley]

Hi Umut -

Sounds like maybe an attribute mapping problem.

Our service definition for Zoom transmits these attributes/mappings:

allowedAttributes:
> {
>   @class: java.util.TreeMap
>   givenName:
>   [
> java.util.ArrayList
> [
>   urn:oid:2.5.4.42
> ]
>   ]
>   mail:
>   [
> java.util.ArrayList
> [
>   urn:oid:0.9.2342.19200300.100.1.3
> ]
>   ]
>   sn:
>   [
> java.util.ArrayList
> [
>   urn:oid:2.5.4.4
> ]
>   ]
> }


This translates to these settings within Zoom -> Admin -> Advanced ->
Single Sign-On

First name   urn:oid:2.5.4.42
Email address  urn:oid:0.9.2342.19200300.100.1.3
Last name  urn:oid:2.5.4.4

[cas-user] CAS 5.3.14 java.util.Collections$UnmodifiableList.get(Collections.java:1311)

[Brian T. Huntley]

Hello - 

We're running CAS 5.3.14 with the self-executing cas.war on CentOS7 and 
OpenJDK 1.8.0-232-b09  The war file was built with the maven overlay.

This environment has has little change since November, but just in the last 
few weeks, we have started to see more and more errors like this that 
causes CAS to become non-functional and return 500 errors to clients:

cas.war: 2020-01-30 08:19:20,909 ERROR [org.apache.catalina.core.
ContainerBase.[Tomcat].[localhost].[/cas].[dispatcherServlet]] - 
cas.war: java.lang.StackOverflowError: null
cas.war: at java.util.Collections$UnmodifiableList.get(Collections.java:1311

) ~[?:1.8.0_232]
cas.war: at java.util.Collections$UnmodifiableList.get(Collections.java:1311
) ~[?:1.8.0_232]



All Google has been able to tell me is a memory issue, but the CAS 
dashboard indicates I have between 1-2GB of Java heap available.

A restart of CAS resolves the issue for a few days.

Anyone else ever run into this?

Thank you!
Brian
