Logon failure: unknown user name or bad password

I have recently installed Notes 8.0.2 on MS Vista Machine.fyi, due to issues with ‘UAC’ - for the purposes of this test - I am actually signed on as the ‘Local Administrator’ - hence I don’t think this is another UAC error…

I have a program that imports emails into another system. When opening, on a form that has a PostOpen of:

@Command([ToolsRunMacro]; “Sieb Export RTF”);

@PostedCommand([ToolsRunMacro]; “(SiebelController)”)

And at some other points later in the processing, it errors with:

“Login failure: unknown user name or bad password”

It looks like a Notes error as at the top it says “IBM Lotus Notes”.

I am singed in with my id, and i can access my mailfile fine for example…

The relevant agents include a LS one, here is the line that occours before the error:

Call uiws.EditDocument(False, newdoc)

Any ideas why that would give me an error?

Any ideas what the error could be related to?
