Unable to edit in Excel with LDAP authentication

SA-12237

Summary



When connecting to the system using LDAP authentication, which goes through a WebSEAL reverse proxy, users are unable to edit content exported to Excel. 

Error Messages



Unable to download prexcelgenerictemplate.biw

Steps to Reproduce



Attempt to export to Excel to edit content.

Root Cause



The root cause of this problem is defect or misconfiguration in the operating environment. The cookie attribute "httponly" prevents sharing of cookie information with other processes. This prevents the Office integration from working properly.

Resolution



The explanation for this behavior is as follows:
Refer SA-8817 for a detailed description of this issue: https://pdn.pega.com/support-articles/error-when-trying-edit-data-table-excel​

Remove the "httponly" cookie attribute. However, this may not be appropriate for a fully secured application as this is a valid cross-site scripting (XSS) security measure. In such systems, provide an alternative method to edit content.
