Pierangelo, I'm sorry. I can confirm that ldapadd was built alongside slapd whose version I stated in my original post (2.3.35). As I'm not at home at the moment, the only thing I can do is extract the syslog of that import in question which admittedly doesn't say much, however, here it goes: Oct 10 02:16:19 mm slapd[9746]: slapd starting Oct 10 02:16:31 mm slapd[9746]: conn=0 fd=8 ACCEPT from IP=192.168.0.3:40394 (IP =0.0.0.0:389) Oct 10 02:16:31 mm slapd[9746]: conn=0 op=0 BIND dn="cn=root,dc=somedomain,dc=or g" method=128 Oct 10 02:16:31 mm slapd[9746]: failed to open file "/var/lib/openldap-data/dc=s omedomain,dc=org/cn=root.ldif": No such file or directory Oct 10 02:16:31 mm slapd[9746]: conn=0 op=0 BIND dn="cn=root,dc=somedomain,dc=or g" mech=SIMPLE ssf=0 Oct 10 02:16:31 mm slapd[9746]: conn=0 op=0 RESULT tag=97 err=0 text= Oct 10 02:16:31 mm slapd[9746]: conn=0 op=1 ADD dn="dc=somedomain,dc=org" Oct 10 02:16:31 mm slapd[9746]: conn=0 op=1 RESULT tag=105 err=0 text= Oct 10 02:16:31 mm slapd[9746]: conn=0 op=2 ADD dn="ou=My address book,dc=somedo main,dc=org" Oct 10 02:16:31 mm slapd[9746]: conn=0 op=2 RESULT tag=105 err=0 text= Oct 10 02:16:31 mm slapd[9746]: conn=0 op=3 ADD dn="cn=With/Slash,ou=My address book,dc=somedomain,dc=org" Oct 10 02:16:31 mm slapd[9746]: conn=0 op=3 RESULT tag=105 err=32 text=Parent do es not exist Oct 10 02:16:31 mm slapd[9746]: conn=0 op=4 UNBIND Oct 10 02:16:31 mm slapd[9746]: conn=0 fd=8 closed Raphael, It is! Did I miss a hint which would have told me not to use back-ldif or use it differently? Reinhold
