Hi, Please change the RALPP contact string to: ldap://site-bdii.pp.rl.ac.uk:2170/mds-vo-name=ralpplcg2,o=grid The change has been made to the GOC and: ldapsearch -x -H ldap://site-bdii.pp.rl.ac.uk:2170 -b 'Mds-vo-name=ralpplcg2,o=Grid' seems to produce the correct output. Thanks, Chris. -- Chris Brew ([log in to unmask]) +44 1235 446326 Particle Physics Department Rutherford Appleton Laboratory Chilton, Didcot. Oxfordshire. OX11 0QX. United Kingdom.
