[K12OSN] Error trying to change group membership

[Krsnendu dasa]

This is the command and error that I get:

[root at k12ltsp1 ~]# smbldap-usermod -G students,staff,513,BackupPC krsnendu
erreur LDAP: Can't contact master ldap server (IO::Socket::INET:
connect: No route to host) at
/usr/lib/perl5/vendor_perl/5.8.8/smbldap_tools.pm line 282.

It is unusual that the error message starts with French.

usershow works fine.
