cpuminer cannot connect to several BTC pools

cpuminer-rplant 5.0.36L

The first issue, miner version is not reported in --version:

$ ./cpuminer-sse2 -V

 built on Oct 16 2023 with GCC 13.2.0
 features: x86_64 SSE2 AVX AVX2 XOP

libcurl/7.84.0 OpenSSL/1.1.1q zlib/1.2.11 c-ares/1.17.0
jansson/2.6

The main issue, cpuminer cannot connect to many BTC pools.

The test script:

$ cat test-btc.sh 
#!/bin/sh

WORKER="TEST"

MINER="./cpuminer-sse2"
#MINER="./minerd"  # pooler cpuminer

$MINER -V
$MINER -a "$ALGO" -o "$POOL" -u "$USER" -p "$PASS" $OPTS "$@"

The test scipt has configuration for 4 different mining pools and cpuminer can connect only to the fist one, solo.clpool.org but it is rejected from the rest.

Difference is in parameters for method mining.authorize, it looks like many pools do not accept extra parameters...
