Hi,
I’m using the unique overlay on OpenLDAP 2.4.30 on Solaris 11.3 like this:
overlay unique
unique_uri
ldap:///ou=Ethers,dc=mydomain,dc=com?macAddress?sub?objectClass=ieee80
2Device
to force the macAddress to be unique.
This works well, except if I attempt to swap the macAddress between
two entries in a single LDAP modify operation, like this:
dn: cn=host1-eth0,ou=Ethers,dc=mydomain,dc=com
changetype: modify
replace: macAddress
macAddress: <current host1-eth1 value>
dn: cn=host1-eth1,ou=Ethers,dc=mydomain,dc=com
changetype: modify
replace: macAddress
macAddress: <current host1-eth0 value>
That's two separate modify operations, not a single operation.
Well it's the only way I know to swap the macAddress with a single ldapmodify command.
I get:
ldap_modify: Constraint violation (19)
additional info: some attributes not unique
Is there a way to swap two values without tripping this error?
Seems unlikely. Why don't you rename the entries instead?
Yes I suppose that's the only way to do this. Thanks for the suggestion. The LDIF has been automatically generated by the ldifdiff.pl script, I'll approach the author to see if it’s a change that could be made easily.
Thanks,
Mark.
