The Sun Directory Services is provided with two SNMP agents:
An SNMP agent that supports the Mail And Directory MANagement (MADMAN) standard (RFC 1565 Network Services Monitoring MIB and RFC 1567 X.500 Directory Monitoring MIB), called dsnmpserv
An SNMP agent called dsnmprad that supports the RADIUS Accounting Server Management Information Base (MIB) described in draft-ietf-radius-acc-servmib-01.txt, and the RADIUS Authentication Server MIB described in draft-ietf-radius-auth-servmib-01.txt
For the full list of management statistics you can obtain from the SNMP agents, refer to "Monitoring Directory Services with SNMP".
