There seems to be a linking issue with libldap in x2goclient from
https://build.opensuse.org/package/show/X11:RemoteDesktop:x2go/x2goclient:

$ x2goclient 
x2goclient: error while loading shared libraries: libldap.so.2: cannot open
shared object file: No such file or directory

$ ldd /usr/bin/x2goclient  | grep ldap
    libldap.so.2 => not found


Installing the package manually does *not* solve the issue:

# zypper in libldap.so.2
