runInstaller does not show osasm group

Hi All,

Am running into strange issue when i configure GRID Infrastructure on single instance.

While going to selecting "Privileged Operating System Groups", i could not select asmadmin group as it does not show up the group at all.

however, i could see the asmadmin group in os group.

i did try delete and recreate both user and group, but still not showing up...am running out of ideas now

here is the steps

[root@fc12ora112 ~]# id grid

uid=502(grid) gid=501(oinstall) groups=501(oinstall),502(dba),504(asmadmin),505(asmdba),506(asmoper)

[root@fc12ora112 ~]# userdel grid

[root@fc12ora112 ~]# groupdel asmadmin

[root@fc12ora112 ~]# useradd -g oinstall -G asmadmin,asmdba,asmoper,dba -c "Grid Infrastructure Owner" grid
