error when importing users "in Russian" from LDAP.
In GLPI 0.90.1, the situation has changed, and if the username is in Russian, and the login is in English. no problems,
User: "Ivanov Ivan Ivanovich",
First name: "Ivan",
Last name: "Ivanov",
Full name: "Ivanov Ivan Ivanovich",
Login name: "[email protected]".
But if the login is in Russian ([email protected]) then GLPI writes: "Login is invalid. Unable to add user."
Also, if the user is not imported, and a connection with AD is configured, then you can log in immediately under the domain account, only if it is in Latin, if the login contains Russian letters, there will be an error.
How to fix this error?
