The reason is that SuSE modified the useradd interface program from 7.x
to 8.x. Usernames with "dots" are no more accepted, although everybody use
it.
I´ve got the same problem and as I didn´t receive ANY help from this
list ( besides saying "this is not a security related question") neither
from SuSE Support Team, I had to edit useradd source code by myself.
Good luck,
