title: create a local user in jenkins along side LDAP authentication
body: <p>The purpose is to create a local user in jenkins(granting admin rights) along side the LDAP group authentication so that this "local" user can perform all admin actions whenever the LDAP authentication is not working.
  I can set up active directory user(valid users with a valid id), but i want to explore the possibility of setting  up "local" jenkins user
  I tried to figure this out through JENKINS JIRA but there is no mention of jenkins local user.</p>
  
  <p>Can anyone help me figure this out.</p>
