Description of problem:

 1. LDAP user is the part of User Group with a custom role having view permission.

 2. Login to Satellite WebUI as an LDAP user shows the following error:
 
~~~
Permission denied
    You are not authorised to perform this action.
    Please request one of the required permissions listed below from a Satellite administrator:

view_hosts"
~~~
 
 3. After successful login from step 2, the user gets removed from the user section in the user group.
  
     Satellite WebUI -> Administer  -> User Group -> Edit any User Group -> under the 'User Group' tab we see 'Users' with 'All items' and 'Selected Items' sections.
   
     The user gets removed from the 'Selected Items' after login as an LDAP user.
 
 4. However, refreshing the 'External Group' creates a user as it is in the user group section.
 
     Satellite WebUI -> Administer  -> User Group -> Edit any User Group -> External Group > Refresh
	 
The issue gets resolved after assigning the same role manually to the user from:
   
     Satellite WebUI -> Administer  -> User -> Edit User -> Roles -> Select from 'All Items'
