Cisco Cisco Web Security Appliance S380 Release Notes

You must reboot the Web Security appliance after you upgrade AsyncOS for Web.

This section describes changes in behavior from previous versions of AsyncOS for Web that may affect 
the appliance configuration after you upgrade to the latest version.

With LDAP authentication and External Data Loss Prevention configured on the appliance, AsyncOS 
now sends the X-Authenticated-Groups header in this format: 

LDAP://(LDAP server name)/(groupname). 

Previously, the format was LDAP://(groupname). This software change may require changes to policies 
or other automation relying on the X-Authenticated-Groups header. [Defect: CSCum91801]

Perform preupgrade requirements, including updating the RAID controller firmware.
