[Koha-devel] Authority Linking

On a fresh marc21/zebra/dom install. I found that after linking bibs to authorities the link appeared bib->authority but all authorities showed 0 biblios linked. Zebra was not recognising 'Koha-Auth-Number' Changing ccl.properties entry Authority-Number 1=Koha-Auth-Number an Authority-Number Koha-Auth-Number Authority-Number to Authority-Number 1=8910 an Authority-Number Koha-Auth-Number Authority-Number fixed this (8910 being the value of Koha-Auth_Number in biblios/etc/bib1.att. My question is this cause or a symptom of a larger problem in the attribute definitions. Cheers Colin
