I've been using memcache since forever and for the very first time I have to setup a installation with SASL support.


but when I try to connect to the memcache using the command memstat I cannot authenticate.

memcstat --servers="127.0.0.1" --username="patrick" --password=123123

When I check the Journal I get these messages:
Nov 09 21:42:51 MP4-MEMCACHE systemd-memcached-wrapper[1882]: Initialized SASL.
Nov 09 21:43:22 MP4-MEMCACHE systemd-memcached-wrapper[1882]: SASL (severity 2): Password verification failed

When I check the daemon status I get these messages:
Nov 09 21:45:53 MP4-MEMCACHE systemd-memcached-wrapper[1882]: Unknown sasl response:  -20

Does anyone could help me to this this issue?
I already tried to create other users but the result is always the same.

Found out the issue
The sasl is adding the server name in lowercase after the username. I know that this could happen but my server name is in uppercase :(
