Custom login permalink

Hi, I’m new to discourse. I’m using the LDAP plugin for login purposes in my forum. I wanted to redirect my users to my LDAP login page instead of the welcome page. I also want my user to get redirected to the LDAP login page instead of the topics table page when he logs out. Is there anyways I can redirect the /login permalink to /auth/ldap. Note I had disabled the welcome message page in customize login options. Thanks, in advance.
