question regarding linux mount

I have directory which is mounted to cifs share via /etc/fstab file, the directory has permission has shown below when it is not mounted.

# ll
total 11509
drwxrwxrwx 2 applmgr dba 198 Apr 28 01:26 HFM_BPC_TRIGGER_FILES

when i do mount -a, immediately the above directory owner changes to root as shown below

# mount -a
# ll
total 11510
drwxr-xr-x 1 root root 4096 Apr 28 01:38 HFM_BPC_TRIGGER_FILES

here is the /etc/fstab file entry for the about mount point
//windowserver/BPC/ /oracle/HFM_BPC_TRIGGER_FILES cifs rw,credentials=/opt/int9/.pass,file_mode=0644,dir_mode=0755 0 0

when the folder is mounted i want the file permission to be retained as shown below

drwxrwxrwx 2 applmgr dba 198 Apr 28 01:26 HFM_BPC_TRIGGER_FILES

how can i achieve this ?

mount always mounts everything as root. Or, more correctly, the owner of the mount point becomes the owner of the directory that is mounted there. When mounting a file system, that will be / so owned by root.

Hi,

you can create the mount point: HFM_BPC_TRIGGER_FILES

using the applmgr userid.

Just before EE went down, I tried to post that cifs mounts have a uid option (which does accept user names as well as numbers). It also has forceuid for when the remote system tries to send a uid. See man 8 mount.cifs

It actually accepts user names, but only in multiuser mode, i.e. not in fstab

Weird

Exactly. numbers are much safer...
