I've installed GroupWise server with eDirectory on SLES 10. Now, I need to
grant file-system rights to an eDirectory user. But after searching the
forums, I found that it is not possible to grant the file-system rights to
an eDir user unless I install OES and create NCP share. If I install OES,
I can create NCP share and grant rights to eDir user of that NCP share,
since NCP share can be mounted as a volume.

My concerns are:
1. Is it possible to install OES on an existing SLES 10 m/c?
2. Is it necessary to install eDir while installing OES? If yes, if I
install OES with eDir, would the existing eDir be affected?
3. Could I grant file system rights to an eDir user after installing OES
and creating NCP share?
