Do you mean during registration or during digest authentication?
During digest authentication youtell OpenSer with realm to use or let the 
client choosing it:
  www_challenge("","1");
  www_challenge("domain","1");

Yes, they will fail in any operation that looks for that user since 
using "use_domain=1" the user is mached if username and domain match, not 
jsut the username.

Note that hashed password were created using the user, domain and clear 
password. If you change the domain, the already created hash will not work if 
you use:

modparam("auth_db", "calculate_ha1", 0) 
modparam("auth_db", "password_column", "ha1")
modparam("auth_db", "password_column_2", "ha1b")
