Some tests were run on charon, the LDAP server, to address some issues of slow response. The server was disconnected from the LAN from 8:10 to 8:25 to test the network hardware.
The problem was corrected by 9:00.
It was found that the network interface on charon (hme) was running at 100 Mbps, Half-duplex.
The interface was reset with the follwoing commands:
ndd -set /dev/hme adv_100fdx_cap 1 ; set 100 Mbps, Full Duplex
ndd -set /dev/hme adv_100hdx_cap 0 ; disable 100 Mbps, Half Duplex
ndd -set /dev/hme adv_10fdx_cap 0 ; disable 10 Mbps, Full Duplex
ndd -set /dev/hme adv_10hdx_cap 0 ; disable 10 Mbps, Half Duplex
ndd -set /dev/hme adv_autoneg_cap 0 ; disable autonegotiation
