原因

This is a LDAP integration issue. Specifically, the errors indicates a problem with Case Sensitive Usernames.

ソリューション

Use the option to force imported usernames to be lowercase and subsequently re-sync the users:

To force lowercase usernames, carry out the following steps:

1. Log into Fisheye's Admin Interface.
2. Under Authentication settings, the option Force Lowercase Username can be toggled on and off.
3. With this setting switched On, when new users are added to Fisheye from an external authentication source, all usernames will be converted to lowercase.
