Pretty much what it says on the tin: adding a user always gives me this message (but the user is created anyway):
Houston, we've had a problem.
Error running a command. cmd = /usr/bin/smbpasswd -s -a MYNEWUSERNAME. rc = 1. stdout = . stderr = /usr/bin/smbpasswd: /usr/lib64/samba/libreplace-samba4.so: version `SAMBA_4.4.4' not found (required by /lib64/libwbclient.so.0) /usr/bin/smbpasswd: /usr/lib64/samba/libwinbind-client-samba4.so: version `SAMBA_4.4.4' not found (required by /lib64/libwbclient.so.0)
Doesn’t matter if I add the user with web login rights or not, doesn’t care about the shell I set.
Edit: I think this issue is related to this one.
