404 Not Found when trying to access mysite/Shibboleth.sso/Session

Thu Jul 23 15:46:54 EDT 2015

Hi, I installed my shibboleth sp last week and everything worked fine 
but then I installed an idp and in the process I made some changes of 
which I didn't keep track. Right now when I try to access to 
mysite/Shibboleth.sso/Session, I get a 404 error. I found in some other 
posts that this means that there are probably problems in my apache 
config, which is really possible in my case since I wasn't too sure what 
I was doing when I was trying to configure my idp.

Here is a part of my apache log :

`debian.privatedns.com' does NOT match server name!?

There is also this that appears in my native.log

2015-07-23 15:42:27 DEBUG Shibboleth.Apache [11284] shib_handler: mapped 
http://kohaprod.inlibro.net/Shibboleth.sso/Session to default

Im pretty sure that my shibd is running properly since this appeared in 
shibd.log when I started shibd :

2015-07-23 14:58:40 INFO Shibboleth.Listener : listener service starting

and also because when I do a ./opt/shibboleth-sp/sbin/shibd -t, all I 
get is this :

2015-07-23 15:28:14 WARN Shibboleth.SessionCache : cacheTimeout property 
is deprecated in favor of cacheAllowance (see documentation)
2015-07-23 15:28:14 WARN Shibboleth.AttributeExtractor.XML : attribute 
mappings are reloadable; be sure to restart web server when adding new 
attribute IDs
overall configuration is loadable, check console for non-fatal problems

Do you have any idea about what could be causing my problem? Any help is 
greatly appreciated!
