User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; fr; rv:1.8.0.9) Gecko/20061206 Firefox/1.5.0.9 Build Identifier: 1.5.0.9 I ve created an entry for LDAP, correctly because when i opened a new mail i click on contacts and i type the first entry letter and it gives me my contact, but if y type directly in then normal zone whitout clik on contatcs button, it dont retrieve my ldap contact. So i close my new mail and return in the général menu of thunderbird, "tools" and "parameters", go then "Redaction and adress", i change parameters to activate "Use a different LDAP server", and click ok. Then open a new mail, type first letter of my ldap contact, and it's good. Now thunderbir find in my personnal book and in the ldap server. So it's work because i've only one ldap server, but if you've got many ldap servers, this parameters don't work that's normal because i force the ldap server. Reproducible: Always Steps to Reproduce: 1.create entry for ldap server 2.find contact in a new mail it don't work 3.modify parameters as discribed before 4.retest it's ok
