security of a pdf file

[brandeau]

hello,
when i open a pdf file (pdf1) with acrobat, I can see everything is authorized : menu file - propertiers - security : add signature is authorized
when i open a pdf file (pdf2) with acrobat, I can see : menu file - propertiers - security : add signature is UNauthorized

with the dll spire.pdf

I can't see any difference???
permissions for the 2 files is 2876 (default)

any idea?
