edpa.exe enumerating user's AD groups on system power on

Created: 16 Apr 2013 | 4 comments

We have some behavior I can't explain which has been producing significate network impact. We have traced our issue to edpa.exe perform LDAP group enumeration AD groups of logged in users. This is generating a signifcate amount of LDAP traffic across my orginization. Everything from security groups to distribution lists that the logged in user belongs to is being enumerated by DLP. This happens once when the computer is powered on. Has anyone seen this behavior and what could be causing it?

Hi Blue,

Plz contact emidiately to symantec support as this was new issue to me. This might be the DLP product (Agent vulnerability or bug). I recommend that u need get more guide/advice from them meanwhile u can collect and analyzed the logs from agent and servers related to this event.

This seems to be standard behavior if you have an LDAP group setup in the console. I believe it does a recursive lookup because groups can be a member of other groups.  I do wish there was an option to turn this off, or set a refresh interval on it.
