ufal/Shibboleth issues update

[milanmajchrak]

Problem description

According to issue from UFAL: ufal#1066 I guess we need to update some functionalities:

• 1.3.1. Create documentation how to configure discojuice
• 1.3.1.2. Show login modal instead of redirecting to /login page
• 1.3.2. After shibboleth login the user is not redirected from where the login was initiated
• 1.3.2.8. Actually netId is mandatory - it should not be
• 1.3.2.9.
  1.3.2.9. Email change (documentation)
  Use idp1, “bfu” username to login. Change https://github.com/ufal/dockerized-idp-testbed/blob/c4305f9628230c107f4e4ba7477d3bd1f895e116/ldap/users.ldif#L16 and rebuild the idp -testbed. Use idp1, “bfu” username. Is the email updated or not?

Answer:
Two occurences:

1. The email is in the netid - NO - the user is not find by the netid and also by email
2. The email is not in the netid - YES - the user is find by the neid and the email is updated
