Environment: Compaq Tru64 UNIX V5.1A / COMPAQ Professional Workstation XP1000 I want to authenticate users at a LDAP-server (Windows 2003) using samba. After download samba 3.0.7 from the samba-site the configure commands leads to following error: configure: WARNING: ldap.h is needed for LDAP support checking for Active Directory and krb5 support... yes configure: error: Active Directory Support requires LDAP support Google finds a lot of users who have obtained the same problem, but I do not find a solution. Any ideas? Maybe I have do install some additional subsets of the TRU64? Thanks in advance Werner Rost
