A user has defined connection object for a file system for RA.BO, then he wanted to change default path.
When trying to save the modification the systems ask for password, even if the password was not change, nor did the user click on the password window.
In other connections object the pass only needs to be entered if you actually change it.
Release : 12.3
Component : RA BUSINESSOBJECTS BusinessObjects 4.0.2 HF2
This is a bug
The fix was release in RA.BusinessObjects v4.1.0 which is available for download.
