problem with LDAP

[Luca Ferrari]

Hi all,
I'm trying to install LDAP on a machine, and migrating the existing accounts 
to the LDAP service. When I run the migration tools I got an error:

# ETC_SERVICES=/dev/null ETC_ALIASES=/dev/null ./migrate_all_online.sh

ldap_bind: Invalid credentials (49)
/usr/bin/ldapadd: returned non-zero exit status: saving failed LDIF 
to /tmp/nis.ldif.ZFnBMs7271

The file seems to be created right, but I don't know what that saving failed 
means. Any idea?

Thanks,
Luca
