[Solved] su: /bin/bash: Permission denied

New user created as:

groupadd mygroup
useradd -s /bin/bash -g myuser -m -k /dev/null myuser

When trying to log in:

[root@vserver~]# su - myuser
su: /bin/bash: Permission denied

Solution:

[root@vserver~]# chmod 755 /bin
[root@vserver~]# su - myuser
[myuser@vserver~]$
