lolMiner cannot connect to MiningRigRentals (MRR) - EXP/ETH

lolMiner_v1.46a_Lin64.tar.gz

One more issue with lolMiner and MRR pool. This one is not about client.reconnect. I do not know what is wrong in this case, lolMiner doesn't have any parameter for troubleshooting (like --debug, --verbose, --protocol-dump). I first found this problem when I tried to mine ETH but I use example for EXP, the same algo and the same result. Error is Error: Worker not authorized, it means that miner uses credentials in a wrong way.

Example:

$ cat mine-exp-mrr-6.sh
#!/bin/sh

# EXP@MRR

POOL="eu-de01.miningrigrentals.com:3344"

USER="droidMiner.218797"
PASS="TEST6"

ALGO="ETHASH"
OPTS=""
#OPTS="--worker TEST6"

./lolMiner --algo "$ALGO" --pool "$POOL" --user "$USER" --pass "$PASS" $OPTS "$@"

$ sh mine-exp-mrr-6.sh --nocolor

Proof, that miner configuration is correct, miniZ can mine at MRR:

$ cat test-exp.mrr-7.sh
#!/bin/sh

# mine some ETHASH crypto @ MRR

POOL="eu-de01.miningrigrentals.com:3344"

USER="droidMiner.218797"

ALGO="ETHASH"

./miniZ --par="$ALGO" --server="$POOL" --user="$USER" --pass="$PASS" $OPTS "$@"

UPDATE. I used Wireshark and I see the BUG in lolMiner. It uses username in a wrong way...

Note that lolMiner uses as username only droidMiner, but the correct username is droidMiner.218797!
