[Pdns-users] Strange time drift in log

[Nikolaos Milas]

  Thanks Christian,

I tried to configure, but it fails:
...
configure: error: ldap library (libldap) not found

But there is libldap:

    # find / -name '*libldap*'
    /usr/lib/libldap_r-2.3.so.0.2.31
    /usr/lib/libldap-2.3.so.0
    /usr/lib/libldap_r-2.3.so.0
    /usr/lib/libldap-2.3.so.0.2.31
