  The dynamics of Wilson lines integrated along a warped extra dimension has
been unknown. We study a five dimensional SU(N) pure gauge theory with
Randall-Sundrum warped compactification on S^1/Z_2. We clarify the notion of
large gauge transformations that are non-periodic on the covering space for
this setup. We obtain Kaluza-Klein expansions of gauge and ghost fields for the
most general twists and background gauge field configurations, which break the
gauge symmetry at classical level in general. We calculate the one-loop
effective potential and find that the symmetry corresponding to the subgroup
allowing continuous Wilson lines is dynamically restored. The presented method
can be directly applied to include extra fields. The connection to dynamical
Scherk-Schwarz supersymmetry breaking in warped space is discussed.
