When we install Remedy Installer by default the authentication method for default Relam * is AR, just change the authentication from AR to Local and you must be able to login TSPS using default username/password i.e admin/admin12345.
Please also check the domain name in RSSO default is bmc.com change it to your domain. Thanks!
Make sure you are typing "Admin" username with a capital A, as the login is case sensitive
Thankful for you , now am able to login
