Hi Winnie,
We have a not dissimilar working system here. We have three emi2 CE's,
each of which mount a shared NFS gridmapdir. On the NFS system, we see
this:
[root@mace ~]# ls -lrtd /etc/grid-security/gridmapdir
drwxrwx--- 2 root root 163840 Nov 22 13:16 /etc/grid-security/gridmapdir
On the emi2 CE's we see this:
[root@hepgrid5 gridmapdir]# ls -lrtd /etc/grid-security/gridmapdir
drwxrwx--- 2 root root 163840 Nov 22 13:16 /etc/grid-security/gridmapdir
Regarding glexec, we see this (on the CEs):
[root@hepgrid5 gridmapdir]# ls -lrt /usr/sbin/glexec
-r-sr-sr-x 1 root glexec 147456 May 16 2012 /usr/sbin/glexec
[root@hepgrid5 gridmapdir]#
And this on one CE:
[root@hepgrid5 etc]# grep glexec /etc/passwd /etc/group
/etc/passwd:glexec:x:112:201:gLExec user account to be used with
/usr/sbin/glexec:/:/sbin/nologin
/etc/group:glexec:x:201:
And this on another CE:
[root@hepgrid10 ~]# grep glexec /etc/passwd /etc/group
/etc/passwd:glexec:x:107:107:gLExec user account to be used with
/usr/sbin/glexec:/:/sbin/nologin
/etc/group:glexec:x:107:
And this on the last CE:
[root@hepgrid6 ~]# grep glexec /etc/passwd /etc/group
/etc/passwd:glexec:x:111:201:gLExec user account to be used with
/usr/sbin/glexec:/:/sbin/nologin
/etc/group:glexec:x:201:
All CE's work OK, AFAICS. The uid/gui numbers are no identical across CEs.
