Sorry : error in the last warning example !... "ldap:///o=gov%2cc=pf????x-dnssrv" correct, but because of the default domain search (cf. resolv.conf) - not because of "o=gov,c=pf" (which isn't the dn of a domaine) ... -> give (of course): "ldap://ldap.gov.pf.:389/o=gov%2cc=pf \ ldap://ldap1.backup.gov.pf.:390/o=gov%2cdc=pf \ ldap://ldap2.backup.gov.pf.:389/o=gov%2cdc=pf" -- PE
