# MAKING THE LOGIN NAME CASE SENSITIVE

Set whether or not to make login names used at the time of user authentication case sensitive.
If the checkbox is set to , login names with identical spelling but different cases (upper and lower) will be identified as different login names. Therefore, login names with identical spelling but different cases will be authenticated as user names of different users.
If the checkbox is set to , case sensitivity for login names is disabled. Therefore, identically spelled user names with upper and lower case character differences will be authenticated as the user name of the same user.
If the selected checkbox is changed to , and identical user names with only upper and lower case character differences exist, the user names that have already been registered are identified as user names of different users.
