[Fedora-directory-users] surgery on existing directory

Hi, I have an existing populated directory supporting a live application. The next development version will have some fairly large scale changes - changes to schema, objectClasses, attribute names and attribute values - but I can't lose the actual data we already have. The approach I've been trying is: 1. Use db2ldif to dump the groups and users (the only bit of the data which is 'mine') from the live directory on the live system: /usr/lib/dirsrv/slapd-flame/db2ldif -U -n userRoot -a /opt/backups/original.ldif -s "dc=lse,dc=ac,dc=uk" -s "ou=My Groups" -s "ou=My Users" 2. Edit the ldif file with the changes I need 3. Load the ldif file into a new fedora directory on my development system with ldif2db.pl: /usr/lib/dirsrv/slapd-dam/ldif2db.pl -D "cn=directory manager" -w MYPASS -n userRoot -s "dc=lse,dc=ac,dc=uk" -s "ou=New Groups" -s "ou=New Users" -i /opt/backups/new.ldif ldif2db.pl terminates almost immediately, clearly without having read most of the file. The fedora log shows: [14/Nov/2008:11:35:54 +0000] conn=2 op=1 ADD dn="cn=import_2008_11_14_11_35_55, cn=import, cn=tasks, cn=config" [14/Nov/2008:11:35:54 +0000] conn=2 op=1 RESULT err=0 tag=105 nentries=0 etime=0 If I repeat the operation I get 'operation error'; and if I try to access the directory, it appears to be completely empty. So, two questions: - is this a reasonable way to go about this task, or are there other tools I should use? - any suggestions for debugging? Thanks Graham
