OOB max length of 'user_name ' cannot handle email address exceeding 40 character during External User Self-RegistrationDescriptionCurrent Behavior: When activating External User Self-Registration "com.snc.external_user_self_registration" then entering "email" which has over 40 char during user registration process then the user can not login the portal with the email address. Expected Behavior: The user should login portal with the email address after regisration. Reproduce steps: 1. Install the plugin "com.snc.external_user_self_registration"2. Go to External User Self Regisration > User Registration Configurations(Table: sys_user_registration_config) and create the record.3. Go to Service Portal > Portals and Select "Service Portal"(Table: sp_portal)4. Enter the value of "External user registration configuration"5. Go to SP page6. Click the link "Register" in below "Don't have an account?"7. Enter the over 40 char in email8. Receive the email (showing user_name which was truncated to 40 char)9. Found the user_name will be trancated in customer_contact, so the user can not login with the email_address. Example: email(Maxlength:100) :012345678901234567890123456789@abcdefghijkhmn.jp ・・・48 digit user_name(Maxlength: 40):012345678901234567890123456789@abcdefghi ・・・40 digit Release or Environmentall releaseInstructionsThis scenario is working as expected. The user_name field has the maximum allowed 40 characters length and when the email address given has more than 40 characters, it is truncated and mapped to user_name.user_name can not be increased due to limitation and the user can get the truncated user_name in the email received for registration and user can use the truncated user_name for logging into the portal.
