Ok. I found it. In order for the user to be able to read the login script information for its particular user account, the user MUST have "Read Permissions" property on the object tab of the account's Advanced Permissions within Active Directory. When a user account is created, by default, it automatically receives this permission. The user account I was testing with, happened to not have had that permission set. Ugggh! I hope this info helps any other frustrated soul out there who may be dealing with this issue. :-)
