*Steps to reproduce*
 # Create a {{LOCAL}} user account (using either the Ambari UI or REST API)
{noformat}
POST /api/v1/users
{noformat}
{code:title=Payload}
{ 
  "Users" : {
    "user_name" : "myuser",
    "password" : "hadoop"
  }
}
{code}
 # Change the user's password (using either the Ambari UI or REST API via the users entry point)
{noformat}
PUT /api/v1/users/myuser
{noformat}
{code:title=Payload}
{ 
  "Users" : {
    "old_password" : "hadoop"
    "password" : "hadoop1234"
  }
}
{code}
{code:title=Response}
{
  "status" : 500,
  "message" : "org.apache.ambari.server.controller.spi.SystemException: An internal system exception occurred: java.lang.Long cannot be cast to java.lang.String"
}
{code}

*Cause*
When building the internal request to set the user's password via the UserAuthenticationSource resource provider, the authentication source key is set as a {{Long}}. The UserAuthenticationSource resource provider expects this value to be a {{String}}.

*Solution*
The UserAuthenticationSource resource provider should accept the {{AuthenticationSourceInfo/source_id}} as either a {{Numeric}} or a {{String}} value that ultimately translates to a {{Long}}.
