<p class="MsoNormal"><span style="font-size:11.0pt">Hello!</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">We experienced this issue earlier this year and OCLC was able to help us resolve it. Here is what they shared with us for implementation on our end:</span><o:p></o:p></p>

<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:#2B2E2F;background:white">We've been able to resolve this issue on sites seeing this by making sure there are no other EBSCO stanzas set. That
means also removing the EBSCO LinkSource stanza that used to be at the beginning of the EBSCOHost stanza (it's OK to leave the Option Cookie, just to make sure the default cookie functionality is set like it should be).</span><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:#2B2E2F"><br>

<span style="background:white"> </span><br>
<span style="background:white">You should also remove this HJ line:</span><br>

<span style="background:white"> </span><br>
<span style="background:white">You should also remove the other stanzas you have set with EBSCO, the EBSCOhost stanza should be the only thing set. For example, I see you also have Education Research Complete and Music Index Online, the hostnames and domains
in these are already covered by EBSCOhost.</span><br>
<span style="background:white"> </span><br>
<span style="background:white">Then in your EZproxy admin go to View Server Status and perform the Host Maintenance:</span><br>

<span style="background:white"> </span><br>
<span style="background:white">Clear out anything shown for Orphaned or not used hosts:</span><br>
<span style="background:white">Remove X orphaned hosts that have -1 database indexes (requires EZproxy restart)</span><br>
<span style="background:white">Remove X hosts that have not been used in over 30 days (requires EZproxy restart)</span><br>
<span style="background:white"> </span><br>
<span style="background:white">Then restart.</span><br>
<span style="background:white"> </span><br>
<span style="background:white">If you still see issues then can you send us your complete updated config.txt (plus any include files it might point to), and temporarily add this line to the top of your user.txt so can check to see that the user header is getting
sent to EBSCO:</span><br>
<span style="background:white">oclcsupport:br0825:admin</span><br>
<span style="background:white"> </span><br>
<span style="background:white">If that all looks good you might check with EBSCO on this, they did provide this page for what to check once we see the user header is getting sent:</span><br>
