access permission

hi,

I have an account \(i.e. abc\) which is set up to sftp files from server A to server B; on server B, I have an account \(i.e. def\) which I use to perform various operation which include invoke certain scripts to execute my java programs. These programs use the files received from server A, but the owner of these files are "abc", hence, I have no access right to read/execute these files. Can anyone tell me how I can solve this problem? Thanks in advance!

Create a common group for both of them and add the users who need to access the file to the group. Give required permissions to the group. I am no admin but this is what i feel.

I am sorry to say that I have no control over this, I am fixed with these two accounts and they belong to different groups, I just need to find a way to get around this!

also, I don't know if this is relevant, I am using AIX...and I need those sftp files (by account "abc") to be read/execute by any other users (different groups)
