In mSUGRA where the neutralino LSP is mostly a bino only rather fine-tuned models survive. On the other hand the relic density upper limit can be easily satisfied in models with a Higgsino or wino LSP.8 pages, 3 figures, Invited talk at Physics at LHC, Vienna, July 2004High Energy Physics - Phenomenologytext
