Hello,
we defined a context parameter with type 'sensitive value'.
If we refer to this parameter in the ListFTP process group, we get the
following error after the processor has started its work:
2019-11-28 08:38:55,725 ERROR [Timer-Driven Process Thread-3]

The ftp server shows the following entry:
Nov 28 08:38:55 ftpp01-v pure-ftpd: ([email protected]) [WARNING] Authentication
failed for user [user_xy]
When I enter the password in the password field instead of using the parameter,
there occurs no error.
Regards
Christoph
