Installing two iMS against one iDS
Hello,
I need to install two iMS 5.2 against one iDS 5.0 sp2 on solaris. My question is wether there is anything that could go wrong with the installation of the second one and wether there are any steps that should be taken before proceeding. Is there anything that should be deleted from the iDS? Will the installation process abort when the systemgroups or systemusers are already present in the directory? (Or is it ldapadd -c?). I couldn't find anything on this scenario (which doesn't mean that there isn't anything but that I couldn't find it), so a hint where to look for documentation is appreciated.
In short, are there any settings from the first installation, that should be edited/deleted before proceeding to the installation of the second machine? In cn=config/o=internet/o=NetscapeRoot ?
Thanks for your help

I've done a setup that has 6 Messaging servers pointing a one Directory server and found the safest thing to was point them at a local Directory during the install and then pointing them externally after the install is finished. You need to prep your external Directory first with the dssetup.zip before you can do this. When the install asks to use another Directory server for Users say no.
Then after the install do this as the Messaging server user.
./configutil -o local.ugldaphost -v yourvalue
./configutil -o local.ugldapdeforgdn -v yourvalue
./configutil -o local.ugldapbinddn -v yourvalue
./configutil -o local.ugldapbindcred -v yourvalue
Which will change the Messaging server settings to point externally.
Not exactly the answer to your question but a viable alternative.

Thanks Sean. I have to admit that it is not the answer that I was looking for. I want to avoid installation of local directories. (Actually I did installations just like you did, because there wasn't any iDS 5.x support yet). Did you try installing against a Directory, that had to suffer a previous iMS installation? And what problems did you run into?
Thanks again

I didn't have much luck when I was doing the Messaging 5.1 installs, I'm not sure about 5.2 if the problems I experienced would be fixed or not. I tried the 5.1 installer against an external Directory server and after the second install it ended up breaking the ACI's on the User tree making it pretty much unusable until I could re-apply the ACI's that existed on the Directory before I tried the install. It almost appears that the installer in 5.1 wasn't intelligent enough to detect the existence of the attributes,ACI's that it was trying to write into the Directory ... not good. As I mentioned though I don't know if 5.2 is any better. With my setup the local Directories only keep the local configuration information and the Address Book entries. All my User and Group information is kept on the external Directory server. My only suggestion is try it against a non-production Directory server and keep a LDIF backup handy for quick restores.
Ok, iMS 5.2 installed here after I deleted the internetdb and added an empty o=internet (with just the objectclasses top and organization). 5.2 seems to be intelligent enough to leave the ACIs untouched. I have no idea what o=internet contained (couldn't find anything but the defaultdomain in there), but there was some error during step 30 until I removed it.
