Unable to unlock cmkadmin user


I’m running CheckMK_2.0.0p1 on a Debian 10 server. I’ve locked the “cmkadmin” user and I’m not able to reactivate it and to log in into the console.

I use htpasswd -m htpasswd cmkadmin to define a new, password,
I check the password with htpasswd -v htpasswd cmkadmin and cat htpasswd to check the entry has been updated
I try to log-in on the interface, I get an “invalid credential” error
I check the htpasswd file with cat htpasswd then see the “!” in front oh the hash, and htpasswd -v htpasswd cmkadmin is no longer OK.

Did I missed sth ?


UP, any idea for this issue ?
