End-User Quarantine
Troubleshooting, FAQ, and Support Information
If I am using Kerberos, why are users unable to log on to the EUQ
console with a short name: “domain\user_name”?
Kerberos servers cannot accept user names in the format: Domain\user_name.
Kerberos requires the format: user_name@domain.xxx
If I installed Microsoft Exchange Server and have set multiple mail
addresses for each user, how do I enable EUQ to check multiple mail
addresses for one user?
If you installed one Microsoft Exchange Server together with Active Directory, you can
do the following:
1. Open the table tb_global_setting in IMSVA administrator database and
replace the value of LDAP-->mail_attr from "mail" to "proxyAddresses".
2. Restart all IMSVA services.
How can I speed up LDAP access if the LDAP server is Active Directory?
There are two methods to speed up access. The method you use depends on the port
number you can use: port 389 or port 3268.
Active Directory uses port 3268 for the Global Catalog. LDAP queries directed to the
global catalog are faster because they do not involve referrals to different domain
controllers.
Tip: Trend Micro recommends using port 3268 for LDAP queries to Active Directory.
Active Directory uses port 389 for LDAP query. If one item cannot be queried in one
domain controller, it uses the LDAP referral mechanism to query another domain
controller. Use port 389 if your company has only one domain or if port 3268 is
unavailable.
To use port 3268 for LDAP queries:
1. Click Administration >IMSVA Configuration > Connections. The
Connections screen appears.
2. Click the LDAP tab.
