Restrict user access

Hi there

I have an application user on my system that wants accesses to these file systems as such:

rwx:

/SAPO
/SAPS12
/R3_888
/R3_888B
/R3_888F
/R3_888R

r:
/usr/sap

these are the existing FS permissions Smilie

wnerships:

Code:

[root@H99A100 ~]# ls -ld /SAPO
drwxrwxr-x 64 ZODCIFUSR ODCgrp 12288 Nov 25 11:02 /SAPO

[root@H99A100 ~]# ls -ld /SAPS12
drwxrwxr-x 5 s12adm ODCgrp 4096 Nov  7 13:49 /SAPS12

[root@H99A100 ~]# ls -ld /R3_888
drwxrwxr-x 129 s12adm ODCgrp 4096 Nov 10 09:56 /R3_888

[root@H99A100 ~]# ls -ld /R3_888B
drwxrwxr-x 31 s12adm ODCgrp 4096 Nov  7 15:03 /R3_888B

[root@H99A100 ~]# ls -ld /R3_888F
drwxrwxr-x 43 s12adm ODCgrp 4096 Nov 21 17:16 /R3_888F

[root@H99A100 ~]# ls -ld /R3_888R
drwxrwxr-x 4 s12adm ODCgrp 4096 Nov  7 15:03 /R3_888R

[root@H99A100 ~]# ls -ld /usr/sap
drwxrwxr-x 5 s12adm sapsys 4096 Oct 25 22:16 /usr/sap

the user:

Code:

[root@H99A100 ~]# id ZODCIFUSR
uid=2020(ZODCIFUSR) gid=200(ODCgrp) groups=200(ODCgrp),0(root) context=root:system_r:unconfined_t:SystemLow-SystemHigh

so how do i go by providing user ZODCIFUSR access to the file systems stated above without setting ACLs on the system? (or is ACLs the only way to do it?)

right now, he's in group 0, so he can pretty much access all the FS but this is just a temp workaround

I was thinking of adding the user to supplementary groups on which the FS are grouped (i.e. sapsys, ODCgrp)

please help, if ACLs is the way to do it, please let me know because i am not very good with the commands

thank you
