Permissions issues
I'm hoping this is a pretty simple question. I have a problem were memebers of a group can't delete or overwrite a file. The box is setup several users all part of the same group. Now default umask is 002. The problem I run into is there are processes that add to, del, and over write files. Now if I start this processes and own the files everything works great, but if someone else starts that processes and I own the files it 's hit and miss. Sometimes is works and sometimes there are permissions errors. Any ideas on what could cause this? and yes the processes does have to be ran by other users and its just not practical to change the file owner everytime some else starts the processes nor is it good to set default permissions to rwxrwxrw.
Thanks

PAM_UMASK(8) Linux-PAM Manual PAM_UMASK(8)
NAME
pam_umask - PAM module to set the file mode creation mask
SYNOPSIS
pam_umask.so [debug] [silent] [usergroups] [umask=mask]
DESCRIPTION
pam_umask is a PAM module to set the file mode creation mask of the current environment. The umask affects the default permissions assigned
to newly created files.
The PAM module tries to get the umask value from the following places in the following order:
o umask= argument
o umask= entry of the users GECOS field
o pri= entry of the users GECOS field
o ulimit= entry of the users GECOS field
o UMASK= entry from /etc/default/login
o UMASK entry from /etc/login.defs
OPTIONS
debug
Print debug information.
silent
Don't print informative messages.
usergroups
If the user is not root and the username is the same as primary group name, the umask group bits are set to be the same as owner bits
(examples: 022 -> 002, 077 -> 007).
umask=mask
Sets the calling process's file mode creation mask (umask) to mask & 0777. The value is interpreted as Octal.
MODULE TYPES PROVIDED
Only the session type is provided.
RETURN VALUES
PAM_SUCCESS
The new umask was set successfully.
PAM_SERVICE_ERR
No username was given.
PAM_USER_UNKNOWN
User not known.
EXAMPLES
Add the following line to /etc/pam.d/login to set the user specific umask at login:
session optional pam_umask.so umask=0022
