Combining Signed/Secured .pdf's doesn't accept password

I'm attempting to combine a number of signed & secured .pdf files into a manual type document, however when prompted to enter the password in the combiner, it doesn't accepted either the signature password or the security password. Was tried on a document with only one signature but realistically will have to be performed on documents with multiple signatures.
 
Should it be one or the other or is it a bug or can Acrobat even do this?
 
Thanks in advance

A signed PDF cannot be combined with another PDF. This would invalidate the signature. If you have the signature installed on your system, which is sounds like you do, then the signature can be "Cleared" with a form reset. If this is true then a simple script can be used to reset just the signature. If you don't have the signature installed you'll need a specialized plug-in to clear it. Once the signature is cleared the documents can be combined.

You might be able to use an "Action" to automate the full process of clearing signatures and combining, but I haven't looked at the details. There are other ways to do this. For example, use the IAC to write a VB application that directs Acrobat to clear and combine the PDFs.

That's what I was afraid of. Does Adobe have this "specialized plug-in"?

Adobe doesn't have this plug-in, but I've written one for implementing exactly the kind of workflow you're interested in, i.e., combining signed docs for review. It is not publicly available at this time, but will be some time in the near future.

Please try using the form reset method first.

this.resetForm(["MySignature"]);

If this doesn't work, or doesn't work consistently in your workflow you'll need the plug-in.
