Using the Uves echelle spectrograph at the ESO VLT, we observed the absorption line spectrum of the QSO 0103-260 in the Fors Deep Field. In addition to the expected Lyα forest lines, we detected at least 16 metal absorption systems with highly different ionization levels in the observed spectral range. The redshifts of the metal absorption systems are strongly correlated with the redshift distribution of the high-z galaxies in the Fors Deep Field and with the strength (but not the number density) of the Lyα forest lines. Both the metal systems and the galaxies show clustering at least up to the QSO emission line redshift of 3.365, but only few of these galaxy accumulations seem to form bound systems.
