**Summary**  
Can’t login with LDAP but LDAP test success.

**Steps to reproduce**  
After configured LDAP and test success, then use LDAP username and password login.  
The LDAP settings is

```json
"LdapSettings": {
        "Enable": true,
        "EnableSync": true,
        "LdapServer": "172.29.0.41",
        "LdapPort": 389,
        "ConnectionSecurity": "",
        "BaseDN": "ou=People,dc=ldapdomain,dc=com",
        "BindUsername": "cn=admin,dc=ldapdomain,dc=com",
        "BindPassword": "ldap123456",
        "UserFilter": "(cn=*)",
        "GroupFilter": "",
        "GuestFilter": "",
        "EnableAdminFilter": false,
        "AdminFilter": "",
        "GroupDisplayNameAttribute": "",
        "GroupIdAttribute": "",
        "FirstNameAttribute": "cn",
        "LastNameAttribute": "sn",
        "EmailAttribute": "userPrincipalName",
        "UsernameAttribute": "cn",
        "NicknameAttribute": "displayName",
        "IdAttribute": "cn",
        "PositionAttribute": "",
        "LoginIdAttribute": "cn",
        "PictureAttribute": "",
        "SyncIntervalMinutes": 60,
        "SkipCertificateVerification": false,
        "PublicCertificateFile": "",
        "PrivateKeyFile": "",
        "QueryTimeout": 60,
        "MaxPageSize": 0,
        "LoginFieldName": "",
        "LoginButtonColor": "",
        "LoginButtonBorderColor": "",
        "LoginButtonTextColor": "",
        "Trace": false
    }

```

Use username `cn=user4,ou=People,dc=ldapdomain,dc=com` or `user4` with correct password to login.

**Expected behavior**  
Login success.

**Observed behavior**  
The mattemost’s version is mattermost/mattermost-preview:5.4.0 docker image and E20 license.  
Console got an error `api.user.login.invalid_credentials_email_username`.
