Login Problems for PubMed

[Natalie Wadley]

Yes, there was a discussion on the EZProxy list a few months ago about SSL
certificate issues that cause the behavior I think you are describing, your
image was stripped from my email. The NCBI login page does not render
correctly when proxying to PubMed first. 

Below are 2 summaries of the issue I saved at the time. Even with a wildcard
certificate we had  trouble, our solution was to eliminate the proxy login
for users going to PubMed. 

 

This works for us since we use a custom start URL with an outside tool -
http://www.ncbi.nlm.nih.gov/pubmed?otool=xxxxx - so our users still get
prompted for proxy login by our open URL service later in their search.

"From Chris Zagar at OCLC/EZProxy: "The problem is that
https://www.ncbi.nlm.nih.gov, for which you approve a certificate mismatch,
is including linked content from https://static.pubmed.gov and for which the
browser does not give you the chance to approve the certificate mismatch."

 

Another description by Chris Zagar: "When you use a non-wildcard certificate
in proxy by hostname, you receive browser warnings when you try to access
the proxied version of https websites. As a result, the proxying of
https://static.pubmed.gov will result in the browser seeing a certificate
mismatch that you will not be able to approve, causing the browser to avoid
retrieving the linked content and the resulting page to paint incorrectly."

Subject: [WEB4LIB] Login Problems for PubMed

 

Hi

I was wondering if anyone has seen this problem before.  I've worked with
two patrons who access PubMed via the library website (meaning they
authenticate through the libraries' proxy server before accessing PubMed).
Once these patrons open PubMed they then go to the NSBI Sign In Page.  After
signing in, however, the PubMed window opens in the "log-in" frame instead
of a full window.  This prevents the patron from 
fully utilizing the PubMed website.  
The patron proving the screenshot below had the problem in both Safari and
Firefox.  I also have a Mac but I didn't have any problems using Safari or
Firefox.
The patron was successfully able to log-in PubMed if they did not go through
the library website so I wonder if the log-in problems are somehow triggered
by the proxy url or maybe it is a setting on their computer.
Just wondering if anyone else has seen this issue.
Thanks!

Erin
