<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Running Ubuntu 10.04 LTS Lucid Lynx, creating group names to mount to a Windows share and the GUI is telling me I have some illegal characters in the group names. <br><br>Group names: <br><br>"music_on_compaqd51c"<br>"shared_video_on_compaqd51c"<br>"software_on_compaqd51c"<br><br>etc, etc<br><br>I used the command line to create the groups, and got no errors but when I used the GUI to verify I did the commands right, I got the error about illegal characters. There are no other error messages, but I'm just wondering about allowable characters, before I create more groups. <br><br>Oddly enough, Google didn't turn up any results for rules on user/group names. <br><br>As usual, thanks in advance..........<br></td></tr></table><br>
