Can't update "Device Attr" to window 2008 iSNS server. #44

I found an issue, a target contain multiple Portal address, if we remove a Portal address, target-isns will send a DevAttrReg to remote server, but window 2008 iSNS server return "Source Unauthorized".

The following is a log: test:~# /usr/bin/target-isns -d -f -i 10.40.3.139 0.000001 I: target-isns version 0.6.5 started 0.000037 I: iSNS server is 10.40.3.139:3205 0.001556 D: iSNS connection opened (fd = 7) 0.002183 D: registering target (all) 0.002198 D: source attribute set to iqn.1994-11.com.net:test-ted:55c60bbe:group2 0.002213 D: gen header DevAttrReg: len = 716, flags = 0x8c00, tx = 1, seq = 0 0.002239 D: sending last PDU seq 0, length 716 0.017133 D: got header DevAttrRegRsp: len = 660, flags = 0x4c00, tx = 1, seq = 0 0.017169 D: iqn.1994-11.com.net:test-ted:55c60bbe:group2 is a target 0.017191 D: iqn.1994-11.com.net:test-ted:8dcf8729:group1 is a target 6.591734 D: inotify[D] iqn.1994-11.com.net:test-ted:8dcf8729:group1/tpg1/192.168.1.22 8.591788 D: registering target iqn.1994-11.com.net:test-ted:8dcf8729:group1 8.591824 D: gen header DevAttrReg: len = 392, flags = 0x9c00, tx = 2, seq = 0 8.591834 D: sending last PDU seq 0, length 392 8.593320 D: got header DevAttrRegRsp: len = 4, flags = 0x4c00, tx = 2, seq = 0 8.593337 E: error in response (status = 8) 15.964334 D: inotify[D] iqn.1994-11.com.net:test-ted:8dcf8729:group1/tpg1/10.40.0.194 15.964589 D: inotify[C] iqn.1994-11.com.net:test-ted:8dcf8729:group1/tpg1/192.168.1.22 17.964382 D: registering target iqn.1994-11.com.net:test-ted:8dcf8729:group1 17.964418 D: gen header DevAttrReg: len = 392, flags = 0x9c00, tx = 3, seq = 0 17.964431 D: sending last PDU seq 0, length 392 17.965350 D: got header DevAttrRegRsp: len = 4, flags = 0x4c00, tx = 3, seq = 0 17.965367 E: error in response (status = 8)

I don't know why windows server will return this error code, is it a bug of target-isns?

Replace packet is not correct, I test window 2008 iSNS and open-isns, the error code of window 2008 iSNS is 8, the error code of open-isns is 3.
