I have made some modifications on Mantis 0.19.2 to add the following feature:
1. login first with the ldap module, if failed, try login with the mysql module
2. reject user with non unique uid in LDAP for login
3. show custom fields in "Show Issues", "Print Reports", "Excel 2000" view
4. custom fields can be choosed in "Printing Options"
Where can I upload the patch? Or check into cvs?
