The power of Virtual environments, I roled back to my pre 2.4 upgrade snapshot and went through this again, steps I followed (for anyones ref) is:
service ldap stop
slapcat -f /etc/openldap/slapd.conf -b "dc=ldn,dc=sw,dc=com" -l /export/home/stuart/full_msldap01.ldif
Managed to rpm -ev openldap-servers-overlays-2.3.43-3.el5 openldap-clients-2.3.43-3.el5 openldap-servers-2.3.43-3.el5
Had to leave openldap-2.3.43-3.el5 32&64-bit versions as they're in too deep.
Removed the empty /usr/lib64/openldap directory which held 2.3 schemas and mv /var/lib/ldap to var/lib/ldap.23, mv /etc/openldap /etc/openldap.23
installed the 2.4 packages
rpm -ivh lib64ldap2.4_2-2.4.22-1.el5.x86_64.rpm openldap2.4-2.4.22-1.el5.x86_64.rpm libldap2.4_2-2.4.22-1.el5.i386.rpm openldap2.4-2.4.22-1.el5.i386.rpm openldap2.4-clients-2.4.22-1.el5.x86_64.rpm openldap2.4-servers-2.4.22-1.el5.x86_64.rpm unixODBC-2.2.11-7.1.x86_64.rpm openldap2.4-extra-schemas-1.3-10.el5.noarch.rpm openldap2.4-servers-2.4.22-1.el5.x86_64.rpm
vi /etc/openldap2.4/slapd.conf /etc/openldap2.4/slapd.access.conf and remov ed unrequired schemas and samba references.
Imported data with
slapadd2.4 -f /etc/openldap2.4/slapd.conf -l /export/home/stuart/full_msldap01.ldif
service ldap2.4 check - OK
service ldap2.4 start - OK
All works and I can login against this LDAP server.
Now - Onto attempting use of slapo-memberof overlay, as mentioned by Quanah.
Thanks guys, I'm sure I'll be back with more questions.
