...making Linux just a little more fun!

I'm beginning the project of upgraded mail hosting. In the process I have to migrate data in old Netscape LDAP server to an OpenLDAP server. I'm newbie in UNIX shell script and my task is mail address book migration. I have only one text file which has data like this:
dn: cn=ldap://:389,dc=yomo,dc=aaa,dc=bbb,dc=ccc cn: ldap://:389 objectclass: top objectclass: applicationprocess objectclass: ldapserver generation: 020000318055502 aci: (targetattr = "*")(version 3.0; acl "Configuration Adminstrators Group"; allow (all) groupdn = "ldap:///cn=Configuration Administrators, ou=Groups, o u=TopologyManagement, o=NetscapeRoot";) aci: (targetattr = "*")(version 3.0; acl "Configuration Adminstrator"; allow ( all) userdn = "ldap:///uid=admin,ou=Administrators, ou=TopologyManagement, o =NetscapeRoot";) aci: (targetattr = "*")(version 3.0; acl "Local Directory Adminstrators Group" ; allow (all) groupdn = "ldap:///ou=Directory Administrators, o=arc.net.my"; ) aci: (targetattr = "*")(version 3.0; acl "XXX Group"; allow (all)groupdn = "ld ap:///cn=slapd-yomo, cn=Netscape Directory Server, cn=Server Group, cn=yom o.aaa.bbb.ccc, ou=aaa.bbb.ccc, o=NetscapeRoot";) modifiersname: uid=admin,ou=Administrators,ou=TopologyManagement,o=NetscapeRoo t modifytimestamp: 20000318055506Z dn: un=RMohana4bdbd8,ou=sharonscy,ou=People,o=aaa.bbb.ccc,o=aaa.bbb.ccc,o=pab un: RMohana4bdbd8 objectclass: top objectclass: person objectclass: organizationalPerson objectclass: inetOrgPerson objectclass: pabperson memberofpab: AddressBook3e0c2d8 mail: rmohan@aaa.bbb.ccc givenname: R. sn: Mohan cn: R. Mohan creatorsname: uid=msg-admin-1,ou=People,o=aaa.bbb.ccc,o=aaa.bbb.ccc modifiersname: uid=msg-admin-1,ou=People,o=aaa.bbb.ccc,o=aaa.bbb.ccc createtimestamp: 20050622142039Z modifytimestamp: 20050622142039Z
After I reviewed the files I found that each box entries has "objectclass: pabperson" is box entries of email address book so at first I want to detect the "objectclass: pabperson" and cut all its box entries. For each box entries is separated by the new line. please you give me any pointers on how to do this successfully by using shell script?
Thank You,
Toppu

If this structure will stay the same for all entries something simple like:
grep -A 4 "objectclass: pabperson" should write exactly: memberofpab: AddressBook3e0c2d8 mail: rmohan@aaa.bbb.ccc givenname: R. sn: Mohan cn: R. Mohan
for each entry to STDOUT. If you would like to suppress certain entries again (like adressbookname) you can pipe this thouh another grep:
grep -A 4 "objectclass: pabperson" | grep -v memberofpab -v beeing "don't show match" and not "verbose" for grep.
Apart from simple line based filter matchings like the above me personally would not try to accomplish something like parsing ldap files by bash-shell scripts. I would go looking into perl and see if there is not an ldap-parsing module available.
I'm sure there are ldap-talking modules for perl, so as long as your old ldap server is still running you could use perl to rip all information directly from the ldap-server and pass it to a new one.

Can you please elaborate on this by providing a more concrete example?

Yes, but I doubt it will be -- there is nothing within LDIF to enforce this, something I've been bitten by before.
