03/26/2020 14 12749
User login SSLVPN was unsuccessful, when using NetExtender and got Error Message "E-mail address may be configured wrong".
OTP (One Time Password) has been enabled on the group the user belongs to, but the user's email address is not configured.
Note: If a Local User does not have one-time password enabled, while a group it belongs to does, make sure the user's email address is configured, otherwise this user cannot login.
Step 1: Navigate to Users | Local Groups. Click the Edit button of the group the user belongs to and check whether option "Require one-time passwords" has been enabled.
Step 2: If "Require one-time passwords" is enabled on the group, please go to Users > Local Users page | Click the edit button of the user | Configure the email address of the user at Setting tab | Click button OK.
How to test:
Reconnect to SSLVPN, an Authentication dialog box will pop up and an Email with one time password will send to your mail box.
After enter the one time password, login will be successful.
