First, the easiest way to get OMSA(the openmanage service) on your box is to add the sara repositories to your apt.
add to the bottom of /etc/apt/sources.list:
deb ftp://ftp.sara.nl/pub/sara-omsa dell sara
Now, (as root) run
to update your package list(from this new repository) then
aptitude install dellomsa
to download and install the package.
Once that is done, you may need to start the service:
If you are running 32-bit, you are done. If you have 64-bit, here is where it gets a lil hairy.
You have to download the following 32-bit debs from the main debian repository. Links provided are for the STABLE branch, if you are running unstable, please find your own links ;-)
After you downloaded each of these 32-bit(i386) debs, extract the files out of them(do not install) with the dpkg -x command. If you can't figure out how to do that, just read the dpkg manual.
dpkg -x libselinux1_1.32-3_i386.deb ./temp
When you are done you should find the following 4 files wherever you extracted them.
Once you find these files, copy the two files that start with "libse" to the /lib32 directory and the two "pam_" files to the /lib32/security directory(you may have to create the security subdirectory).
Now, edit the /etc/pam.d/omauth file and replace the uncommented out lines with the path starting with /lib/security to /lib32/security. It should look something like this when you are done.(ignoring the commented out lines at the top)
auth required /lib32/security/pam_unix.so nullok
auth required /lib32/security/pam_nologin.so
account required /lib32/security/pam_unix.so nullok
One last step! Its an easy one. Just run the command ldconfig. This will update pam to read the new config files(the one you just edited) and now openmanage will be looking in the correct spot!
Now just browse to your web interface:(change IP as necessary). Make sure you use https to browse it, http will not work.
Login as root and BAM you are done.
