While running through the solutions listed here, I noticed some errors that seemed to indicate a problem verifying our SSL certificate. After some checking with our helpful IT staff, I added three lines to /etc/apache2/ssl.conf:
SSLCertificateFile /path/to/certificate.edu.crt
SSLCertificateKeyFile /path/to/certificatekey.edu.key
SSLCertificateChainFile /path/to/crtfile.crt
This seemed to resolve the problem.
Anyone using SSL and having trouble with the Library Browser might find this useful.
