Thank you, it's pointed out, that I accidently set "zsh" as login shell
instead of "/bin/zsh",
I changed it back to normal and everything works fine now.
I reread the NOTE and it's unclear that CURRENT login shell must be listed
since I thought that it means NEW login shell must be listed there.
The only restriction placed on the login shell is that the command
name must be listed in /etc/shells, unless the
invoker is the superuser, and then any value may be added. An
account with a restricted login shell may not change
her login shell. For this reason, placing /bin/rsh in /etc/shells is
discouraged since accidentally changing to a
restricted shell would prevent the user from ever changing her login
shell back to its original value.
