Silly question: (IDM 3.5.1, eDir 8.8 Sp1 FT2, SS205, on SLES)

In password policies, SS205 versions, there is an option:

Maximum number of times a specific character can be repeated
sequentially (1-512).

I need to be sure we never have the same char repeat. (I.e. AA, bb, YY
etc).

Should the value be 0 or 1 here? We have it set to 1, and we got a
Generate Password token result that included YY in the random password.
(Yes it is pointing at the correct policy).
