user own a scedule report -- 2 question

[jive]

Hi,
I found an error this morning telling me a schedule report cannot run because the user authentication failed. It's OK, most company have a schedule to change user password for security reason. For authentication we used LDAP and the user responsible for this report is me. I have to change my password.
1- I want to be sure this is the reason for why the report failed.
2- How did you manage that , did you create user only for running report or there is a way to run a report without authentication.

From what I'm read in the process of ruining a report there is always an identification phase.

Thanks for your help.
