Username with colon prevents user from logging in

[psu1ski17]

An IdenTrust ECA certificate has a colon character in the username field. Entries in file users.properties that have a username field that has a colon character is preventing the user from logging in. The username field is not being parsed correctly.

The following is an example entry in file users.properties of a user with a colon in the username field:

John.Doe:A018A2=password,ROLE_USER,John Doe,,jdoe-email-address,[usergroup;;;active]

File MyDetailsService.java needs to be modified to correctly parse a username field with a colon character.
