We (Ball State University) are in the process of updating our identity provider. We are rolling in the changes so individual systems are being moved from using "shibboleth.bsu.edu" to using "federate.bsu.edu". It is lon-capa's turn.
I found all the files that referenced "shibboleth.bsu.edu" and copied them to a different location:
cp /etc/shibboleth/attribute-map.xml /root/sso/attribute-map.xml.old
cp /etc/shibboleth/shibboleth2.xml /root/sso/shibboleth2.xml.old
cp /etc/shibboleth/metadata/shibboleth.bsu.edu.xml /root/sso/shibboleth.bsu.edu.xml
I then made copies of the two .old files as .new and edited them to replace "shibboleth.bsu.edu" with "federate.bsu.edu"
I also got the new metadata (with wget https://federate.bsu.edu/FederationMetadata/2007-06/FederationMetadata.xml) and saved it as federate.bsu.edu.xml
This morning I stopped shibd, copied the .new files to /etc/shibboleth/ and federate.bsu.edu.xml to /etc/shibboleth/metadata/
I checked for "shibboleth.bsu.edu":
[root at lon-capa01 ~]# grep -H -r -i 'shibboleth.bsu.edu' /etc
[root at lon-capa01 ~]#
which shows that I had eliminated all references to it.
I restarted shibd and when I tried to log in, I got:
Unknown or unusable identity provider
The identity provider supplying your login credentials is not authorized for use with this service or does not support the necessary capabilities.
To report this problem, please contact the site administrator at security at bsu.edu.
Please include the following error message in any email:
Identity provider lookup failed at (https:lonn-capa01.aws.bsu.edu/adm/sso)
opensaml::saml2md::MetadataException: Unable to locate metadata for identity provider (http://shibboleth.bsu.edu/sso)
For some reason it was still looking for the EntityID http://shibboleth.bsu.edu/sso
I did a system reboot but got the same thing.
I reverted to the old files and we are working, but that will only last a couple of weeks before our cert expires for our old identity provider site and it goes down.
I am totally lost. is there somewhere else with shibboleth configuration data?
