Cisco Cisco Email Security Appliance C390

CSCzv18265 Reboot Required to Show Message Tracking Data After resetconfig

No results are shown in Message Tracking after running 

resetconfig

 on an Email 

Security appliance running AsyncOS 7.6 for Email and using 

loadconfig

 to load a 

configuration file. 

Workaround: Reboot the Email Security appliance. All message tracking details will 
appear correctly after the reboot. 

CSCzv85685 The Email Security Monitor Overview Page Incorrectly Counts Quarantine Mails 

When calculating the number of virus-positive messages, the Email Security Monitor 
Overview page includes messages that were quarantined by the anti-virus scanning 
engine due to the message being unscannable or encrypted. These messages are not 
included in the virus-positive report on the Virus Types pages.

CSCzv70453 LDAP Test Query in Domain Assignment Fails If One or More Servers Defined in 

When you run the test query from the Domain Assignment page, the query may 
erroneously tests other servers defined from the Domain Assignments page. If any 
server defined in the Domain Assignments page is unreachable, the query may fail.

CSCzv95624 One or More Unavailable LDAP Servers Can Cause a Chain Query to Fail.

One or more unavailable LDAP servers in a chain can cause the chain query to fail.

CSCzv66584 False Positives with “Transmission of Contact Information” DLP Policy.

A message signature containing the sender's contact information can result in a false 
positive from the “Transmission of Contact Information” DLP policy if a reply to the 
original message resulted in the sender's information appearing multiple times in the 
message body. Workaround: Adjust the policy’s severity scale to increase the number of 
matches before triggering the policy’s actions.

CSCzv95338 AsyncOS Does Not Support Multiple RADIUS Class Attributes.

Currently, AsyncOS supports only one RADIUS class attribute per user. If a user has 
more than one class attribute defined, AsyncOS provides the user access to the GUI 
based on the first RADIUS class attribute only. Ensure that you carefully configure the 
RADIUS server to define the user's group in the first RADIUS class attribute.

CSCzv25323 CLI Does Not Support Usernames Longer Than 16 Characters for Local and 

Currently, the CLI does not support usernames containing 17 characters or more. 
Workaround: Use a shorter username, or enter the username in the GUI, which has no 
such limitation if external authentication is configured.

CSCzv59483 External Authentication Fails if the Group Name Contain Special Characters.

External Active Directory LDAP users cannot long into the IronPort Email Security 
appliance if they belong to an LDAP group that has one of the following special 
characters in the group name: 

# " < > , + \ ;

. Active Directory escapes these 

characters by prepending backslashes (

\

). This issue also affects LDAP group queries.

Workaround: Manually escape these characters during configuration by adding the 
backslash character (

\

) before the special character. For example, if the LDAP group 

name is #Admin, enter 

\#Admin

 when mapping LDAP groups in AsyncOS.
