On the system are 2 users which want to preserve the file modification times of a file when copying this file from a develop system to the production system. Both systems are Linux.
Both users are member of the same group.
umask for the users is 0012
When I use cp -p file /mnt/remotemachine/remotedir/file
It gives an error :
cp: setting permissions for `/mnt/10.31.0.1/xintpro/PROD/xlog/copytest3.test': Operation not permitted

you are trying to copy a file through a samba share which is mounted to your /mnt some directory.

if you use NFS to share the directory and copy and paste files with permissions (assuming the uid and gid are same across machines) then it should work.

when the user is owner of the file on the remote system it works.

Only the owner of a file is allowed to change permissions. This applies to local filesystems & NFS.
However I am uncertain whether non_owner can change timestamps. Instead of using -p, try --preserve=timestamps to answer that.
Another approach: if the user has write access to the directory, he can delete the file and recreate it. Then all attributes may be preserved, including owner.

--remove-destination will remove the targety file before copying. This option and --preserve require a recent cp (since file-utils 4.1)
