I have the same problem. We have to share pdf files with other users. I tested with different Adobe readers (8.x , 9.x ). I tested on RH Linux and on Solaris - always the same result. File permissions after saving are 600 (rw-------) instead of 644 (rw-r--r--). Adobe reader ingores the systems standard umask.
Any help whould be great.
