Shibboleth Idp does not persist URL hash fragments across a login redirect.

TL;DR: on the face of it, this must be an application problem and not a 
Shibboleth problem.

The client never transmits fragments to the SP, so the SP is powerless 
to include any information about the fragment.

Take a look at the packets with HTTPLiveHeaders, which will show you 
what the SP has to work with.

For example, if I go to http://jorj.org/blog/#test, this is what's sent:

	GET /blog/ HTTP/1.1
	Host: jorj.org
	Accept: 
text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
	Accept-Encoding: gzip, deflate, sdch
	Accept-Language: en-US,en;q=0.8
	Upgrade-Insecure-Requests: 1
	User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, 
like Gecko) Chrome/49.0.2623.87 Safari/537.36

The server is completely unaware of the fragment.

But I have no idea what the OP's Angular app is doing.

There are ways that Angular can preserve the fragment during 
authentication (cf. https://github.com/auth0/auth0-angular) and maybe 
there's an interaction problem with something like that and Shibboleth. 
But if there is, someone would have to spell out in great detail exactly 
what's going wrong and where.
