Thank you for your hints! Since I am not familiar with python programming, I did some rough hack that get it working, base on your thoughts.
I added two lines to the original LDAPLogin2 extention.http://www.roundup-tracker.org/cgi-bin/moin.cgi/LDAPLogin2
1, I added "username=username.lower()" under line 184, it looks like below:
def ldap_login(self, username='', password=''):        """Perform a login against LDAP."""        self.auth_method = 'ldap'        username=username.lower()    #this is the line I added.
2, I added "self.client.user = self.client.user.lower()" before line 420, it looks like below:
try:            self.client.user = self.client.user.lower()    #this is the line I added.            self.client.userid = self.db.user.lookup(self.client.user)            # update the empty values with LDAP values
Of cource, as you said, I need also change the existing ldap usernames in the roundup to lower case.After these are done, username of any new ldap users will be lower case, and They can login with both Upper or lower case usernames.
