Hi, I'm currently using 2.2.29, and there seems to be a problem with passwords containing the '#' character - which I happen to like to use very much Updating a user with a new password that contains a '#', gives auth errors in ftp, f.e. Using a password without the '#' works alright. If this is old news for you, just close the thread, I used the search function only for a very quick search.
Never heard of that problem in any version of ispconfig 2. Please post a request in the bugtracker if you want this to be reviewed by the developers.
