RFC password problem: I'm using RFC access to scripts in Web Repository and as of today my password in GuiXT profile is no longer accepted, although I haven't changed it. I know that I need to enclose the password in inverted commas since it contains lower case characters. Is there any change in password handling? I have installed GuiXT 2015 Q1 2 for testing and then the previous 2014 Q3 2 version.

You need to re-enter your RFC password in GuiXT profile. The reason is that the encryption algorithm has changed with the 2015 GuiXT version. The 2015 version understands the old password but when you go back to the 2014 version the password with the stronger 2015 encrpytion is not recognized.
