Has anyone done a NSMS 4.15 to iPlanet MS 5.1 migration on NT?

I have NSMS 4.15 running on NT and, for several reasons, want to move to iPlanet v5.1 on the same system. Using my test server I've been following the instructions that start on p12 of the v5.1 release notes and everything seems to go ok until I actually install iMS. Just after the shortcuts are created for the server console I get a error on the screen.

A serious problem occured while installing the iPlanet Messaging Server Domain Component Tree. It reported the following problem:

The server configuration for the Domain Component Tree cannot be created.

Looking in the installation log I see the following;

(Several of these)

ERROR:

TYPE: Install Config

LOCATION: LInstallConfig::FindExpression

DETAILS: No value exists for the name "local.deforg.dn".

then the Notice: creating ...

and then

NOTICE: Creating Domain Component Tree.

ERROR:

TYPE: LDAP

LOCATION: LLdapEntry::WriteToLdap

DETAILS: Unable to create entry 'o=internet' in LDAP server.

and then

ERROR:

TYPE: Installable

LOCATION: LMetaDataInstallable::Create

DETAILS: The server configuration for the Domain Component Tree cannot be created.

so it appears to me that the install fails as it can' create ldap entries. The slapd logs confirm that.

Any idea why? I'm stumped on this one.

tia, al

Did you run the ims_dssetup utility script on the directory server before attempting the install?It sounds to me like it has not as one thing the ims_dssetp utility does is add the suffix definition to the slapd.ldbm.conf file for o=internet.-Chris
