Internet ID & Password

When you connect to library resources you are asked for your username and password. Your username is your Internet ID (also called your X.500 username or your e-mail username).

To look up your Internet ID, search for your name in the University's Student/Staff directory at: http://www.umn.edu/lookup

If you’ve forgotten your password, you may contact the ITSS TechCenter Helpdesk at 218-726-8847 for help (see Help Desk Hours).


Authentication Problems (logging into Library PCs or using databases from off campus)

1. You have a UMD e-mail account, but are NOT a current UMD student, faculty, or staff.

Currently, authentication is not available for people who are not current UMD students, faculty, or staff. However, the Library does provide guest computers for visitors. Ask at the first floor circulation desk for more information on the guest computers.

2. You ARE a current UMD student or employee, but have not changed your Internet ID (X.500 password) password in a long time.

Change your password at https://www.umn.edu/validate. After a delay (usually about ½ hour) you should be able to log in.

3. Your password does not meet these requirements:

4. You ARE a current UMD student, but have suppressed your address info, including e-mail address.

Change your suppression of personal info to suppressing only address and telephone. This can be done here. A day later, you may re-instate full suppression of personal data. (By then UMD will have received the necessary data to enable authentication for you.)


If you are connecting from off-campus, it is possible that your firewall is preventing access to the Library's databases. One common problem may relate to the ports your computer allows access to. If you are at a workplace, check with your computer security personnel to see whether some ports may have been restricted. Otherwise, check your own firewall software - it should have settings where you can open and close specific ports. Remember that routers may also have a firewall built in, so sometimes you need to look a the documentation for your specific brand and model of router as well.

To use library databases or the Library catalog, allow outbound traffic on port 2443 for login.libpdb.d .umn.edu . If this doesn't completely solve the problem you can also try opening port 2048 .



The library uses a proxy server to grant off-campus access to licensed databases for current UMD students, staff, and faculty. If the computer you are using from off-campus is also running a proxy server it can interfere with the Library's proxy server. A good way to test connection problems with the Library databases is to first verify that you can connect to the Library's proxy server. To do this, go to https://login.libpdb.d.umn.edu:2443 and enter your UMD x.500 user name and password. If you get a message that says "invalid user name or password" when you try this, read the password section of this page.

If you get a "page can not be displayed message" and you are at a work site or a high school, then you should consult with your network administrator. If the appropriate ports have been opened in the organization's firewall, then there may be a competing proxy server in use at your site. The network staff will have to help you select the right settings so the two proxy servers are not in conflict with each other. 

In Internet Explorer use tools =>internet options =>connections tab =>LAN settings to check for proxy serttings.

In FireFox use tools =>options =>advanced =>network tab =>settings button to check for proxy settings.

In Chrome use settings =>"show advanced" (near the bottom) =>under NETWORK =>change proxy settings.

Consult your network staff before changing these settings.

Virtual Private Network (VPN)

You may be unable to use UMD's VPN software if any of the following are true:

In Windows 2000/XP, if you wish to turn off ICS, Click Start >> Settings >> Control panel >> Network Connections.
Right-click on each network connection and select Properties. Select the Advanced Tab; if there is a checked box for ICS saying "Allow other network users to connect through this computer’s Internet connection," uncheck that box.

(Under Windows XP, the built in network bridge is part of ICS and will interfere with UMD's VPN. You may have to turn it off separately.)

In Windows 7, to disable ICS, open control Panel, then click on Network & Internet category to open Network Connections.

Chrome menu

Right-click the shared connection, and then click Properties. If you are prompted for an administrator password or confirmation, type that in.

Chrome menu

Click the Sharing tab, UNCHECK the top box "Allow other network users to connect through this computer's Internet connection" then click OK.



Javascript is necessary for many sites to work properly. To toggle Javascript on or off:

In Internet Explorer, go to
Tools >> Internet Options >> Security >> Custom Level
Scroll 7/8ths of the way down, look for Scripting.
Enable or disable scripting and click Yes and OK as needed.

In Mozilla Firefox, go to
Tools >> Options >> Content Tab
Check or uncheck "enable JavaScript" 
Fine-tune your javascript settings with the ADVANCED button (optional)

In Chrome, go to this menu icon Chrome menu
Select Settings >> Show advanced settings
In the "Privacy" section, click Content settings
under Javascript section, select or deselect radio button “Allow all sites to run JavaScript (recommended)”

In Apple Safari, go to
Edit >> Preferences
Click the Security Tab
Look for the "Enable JavaScript" check box and make your choice

Laptop / wireless users not able to use library resources

Make sure you did not login to the UMD network as a "guest." Guest users are not allowed to access restricted/licensed library resources.  Re-login with your UMD authentication and try again.

eBooks: Catalog Link

Sometimes the catalog URL's linking to an eBook are incorrect or inaccessible via wireless or off-campus. Refer the patron to the native interface (e.g. eBooks on EBSCOhost, SpringerLink) to access the book. Please report the linking problem to Deb by clicking on "Report Cataloging Error", which is located at the Full Record view.

Not recognizing user as UMD

Occasionally a user will try to access a resource we own, but they will be denied access.  For some reason, the necessary EZProxy prefix has either been stripped out of the URL or was never included.  By prepending the EZProxy URL prefix to the resource's URL, users can log in, allowing access to the resource.  Here is the EZProxy URL prefix to insert in front:


The result might look something like this:


Faculty Emeritus Access Problem

Faculty emeritus (FE) are granted remote access to library resources.  The official list of FE is located in the UMD campus directory (print version).  This is the list we use to confirm someones status as a FE.  There are two possibilities concerning access problems concerning FE.

  1. The FE has not used their x.500 username/password to access items other than e-mail in quite a while.  They should contact the ITSS help desk to determine/have their password changed.
  2. Another cause of denied access, although less common, is that the FE has not been flagged as having authority to access the resources remotely. If the first step does not solve their access problem, then please contact Darlene to assist in getting them proper access.

Graduate Students Not Currently Enrolled (no access to library resources)

The graduate student should contact their department about enrolling in GRAD 0999 - Graduate School Active Status.  Fees still apply, but not tuition. This will grant access to the Library resources.

Users Unable to Access from a place of Business

Many businesses have firewalls in place that prevent users from accessing our databases through EZProxy.  They can either use a non-firewalled network computer or have the company's technical support open up ports 2443 and 2048.

Printing and general problems with computer technology in the Library

If you experience trouble with printers, card readers, cash-to-card machines, scanners, or other technology see the ITSS lab consultant at the far-right side of the Circulation desk on the first floor. Their direct phone number is 218-726-8858. If unreachable, try the ITSS Helpdesk at 218-726-8847.

Mac users can't open PDFs from EBSCO databases

There are two solutions available, one for Safari users and one for Firefox users.
