   15: <h1>Login Problems with LON-CAPA</h1>
   16: <h2>Which browsers can I use with LON-CAPA?</h2>
   17: LON-CAPA is designed to work with the following browsers
   18: <ul>
   19: <li>Mozilla version 1.0 and higher</li>
   20: <li>Netscape version 4.7 and higher</li>
   21: <li>Safari</li>
   22: <li>Galeon version 1.2 and higher</li>
   23: <li>Internet Explorer version 5.1 and higher</li>
   24: </ul>
   25: on the following operating systems
   26: <ul>
   27: <li>Linux</li>
   28: <li>UNIX</li>
   29: <li>MacOS</li>
   30: <li>Windows 98, NT, 2000, ME, and XP</li>
   31: </ul>
   32: If you have problems logging in with any browser or any operating system not
   33: listed above, please <b>use another browser or computer.</b>
   34: <h2>I have accessibility needs</h2>
   35: Please use the 
   36: <a href="/adm/login?interface=textual">alternative text-based login mode</a>. 
   37: Please let the system administrator know if you have any problems.
   38: <h2>I would like to use my Pocket Computer or PDA to access LON-CAPA</h2>
   39: While we can make no guarantees that LON-CAPA will work with your particular
   40: Pocket Computer or PDA, you might want to try the
   41: <a href="/adm/login?interface=textual">alternative text-based login mode</a>. 
   42: We have had success with a Sharp Zaurus and Thunderhawk on PocketPCs 
   43: (e.g., Dell Axim).
   44: <h2>I get "Username and/or password could not be authenticated"</h2>
   45: <ul>
   46: <li>
   47: The most common problem here is that the Caps-Lock button is pressed. Usernames
   48: and passwords are case sensitive, so it does matter if something is typed with
   49: lowercase or with uppercase letters.
   50: </li><li>
   51: The second most common problems is that users accidentally go to the wrong 
   52: server. LON-CAPA is running at many universities, colleges, and schools.
   53: Especially if you hit upon this page by looking for "LON-CAPA" in Google or
   54: some other search engine, you might have hit a server at another place. Please
   55: make sure to use the URL provided to you. 
   56: </li></ul>
   57: <h2>I get a list of computers ...</h2>
   58: This means that the server you attempted to login to is currently not 
   59: available. For example, it might be undergoing maintenance. Please click on
   60: any of the other server, giving preference to the ones that say "preferred."
   61: <h2>I get "Information needed to verify your login information is missing, inaccessible or expired"</h2>
   62: LON-CAPA does internal encryption of password information submitted from the 
   63: login screen, but only keeps the decryption information for a day. Simply pull
   64: up the login screen again. 
   65: If that does not solve the problem, please wait for 20 minutes, reload 
   66: the login page, and try again. If after 20 minutes LON-CAPA still gives you 
   67: the same message, please email the Server Administrator listed on the login 
   68: page. The Server Administrator can verify your situation and re-enable logins.
   69: <h2>I hit "Log In," but nothing happens, or I get error messages and 
   70: warnings</h2>
   71: <ul>
   72: <li>The most common problem is that your browser is not one of the browsers
   73: listed above.</li>
   74: <li>You might have modified the preferences in your browser. In particular, the
   75: following preferences can be a problem:
   76: <ul>
   77: <li>Scripting languages, in particular JavaScript, is disabled. 
   78: <i>Test: as you <a href="javascript:alert('PASSED TEST');">click here</a>, 
   79: a small window should appear. If no window appears, scripting is disabled.</i>
   80: </li>
   81: <li>The security settings are cranked up to a higher level. In particular, this
   82: might prevent unencrypted submission of passwords (LON-CAPA actually does its
   83: own encryption), or cross-server submission of forms.
   84: </ul></li>
   85: <li>If all else fails, please <b>try from another computer.</b></li>
   86: </ul>
   87: <h2>After logging in, I get the message "Welcome," but then nothing happens
   88: </h2>
   89: Actually, something <i>will</i> happen if you wait around a little bit: 
   90: after trying 
   91: to launch its Remote Control for a while, LON-CAPA will default into its
   92: text-based interface mode. That mode 
   93: is just fine for most operations, but has certain limits. 
   94: <ul>
   95: <li>The most common problem is that your browser is not one of the browsers
   96: listed above.</li>
   97: <li>If you have a supported browser, it might be hung. 
   98: <b>Please completely quit
   99: your browser, and start it again.</b></li>
  100: <li>You might have installed a filter against so-called "pop-up ads" (those
  101: obnoxious windows that come up into your face trying to sell you something
  102: while you are surfing).
  103: 
  104: We recommend to disable the filter for your school's domain, for example
  105: "<tt>xyzu.edu</tt>." 
  106: <i>Test: as you <a href="javascript:openwin();">click here</a>, 
  107: a small window should appear. 
  108: If no window appears there, but 
  109: <a href="javascript:alert('THIS COMES UP');">this window</a> does come up,
  110: pop-up filters are active.</i></li>
  111: <li>You might be getting your internet access from a free service provider 
  112: which adds banner ads to your pages. These ads conflict with LON-CAPA, you 
  113: will need to use another provider.</li>
  114: <li>If you do not want to re-adjust the preferences of your browser, you might
  115: want to use the 
  116: <a href="/adm/login?interface=textual">text-based login mode</a>. 
  117: <li>If all else fails, please <b>try from another computer.</b></li>
  118: </ul>
