Configure the validation.properties File
SAML responses use characters that might not be enabled in your REGEX. To ensure that characters are enabled in your REGEX, complete the following steps:
1. Edit the validation.properties file in the ThingworxStorage\esapi\ directory.
2. In the validation rules section of the file, add a Validator.HTTPParameterValue entry for requests with a SAMLResponse parameter. If you are using PingFederate as the CAS, this entry should be entered as follows:
Validator.HTTPParameterValue_SAMLResponse=^[a-zA-Z0-9+\/=]*$
If you are implementing any other CAS, refer to your selected CAS product documentation or to SAML standards for characters that are required in SAML responses for your environment.
* 
It is highly recommended that you verify that the REGEX specified in this file does not allow characters that could introduce security concerns in your environment.
