What's this audit.log message mean?

[Baylink]

I see these exactly every 10 minutes in my audit log, and it's the only message I can't intuit the meaning of:

2010-04-24 11:40:03,994 INFO [btpool0-7831://localhost:7071/service/admin/soap/AuthRequest] [name=zimbra;ip=127.0.0.1;] security - cmd=Auth; account=zimbra; protocol=soap;
2010-04-24 11:40:03,993 INFO [btpool0-7831://localhost:7071/service/admin/soap/AuthRequest] [name=zimbra;ip=127.0.0.1;] security - cmd=AdminAuth; account=zimbra;

Clearly, they're coming from some other part of the service on the same server, but I'm not clear what part... and I don't *have* an account named zimbra.

Huh?

Alas, that page is 2.5 releases old, and has no actual detail.

audit logs are your zimbra server authentication logs.

This log contains authentication activity of users and administrators and login failures. In addition, it logs admin activity to be able to track configuration changes.

Yes, I know that. But that's not an answer to the question I asked. :-)
