Issue with User Attribute Retrieval in phpCAS Versions Beyond 1.3.8

[thundersword]

I wanted to bring to your attention an issue I've encountered with phpCAS versions beyond 1.3.8 regarding user attribute retrieval.

After some investigation, I found that in phpCAS version 1.3.8, I am able to successfully retrieve user attributes. However, upon upgrading to later versions, such as 1.6.1, I am unable to retrieve these attributes, despite configuring phpCAS with the same settings.

I've tried various troubleshooting steps, including reviewing the phpCAS documentation, enabling debug mode, and checking for any configuration changes between versions. However, I have not been able to resolve the issue.

It appears that there may be changes in the phpCAS logic or configuration settings in versions beyond 1.3.8 that are impacting the retrieval of user attributes. I've also noticed that rolling back to version 1.3.8 allows me to successfully retrieve user attributes again.

I wanted to bring this to your attention in the hopes that it may help improve phpCAS in future releases. If there are any specific details or logs you would like me to provide to assist with troubleshooting, please let me know.

Thank you for your attention to this matter, and I appreciate your efforts in maintaining phpCAS.
