Subject: Changed the CAS Protocol!  A 'yes' or 'no' first line followed with the user is still... 
X-Git-Tag: 22.4~51
X-Git-Url: https://git.mdrn.pl/django-cas-provider.git/commitdiff_plain/08d3502c8f9a169713122c681d86eb16d9f8c1e6

Changed the CAS Protocol!  A 'yes' or 'no' first line followed with the user is still consistent.

Now, the response has historical identifiers trailing the primary user, each on a new line.

Clients should check for each identifier...
-- if one is matched, use that username
-- if two are matched, merge accounts on client end
-- if none are matched, create a new user with primary username

Old protocol response:
yes
foobar123

New protocol response:
yes
foobar123
barbaz345
barfoo789
