It's been too long - IBM Tivoli Access Manager for e-business ( WebSEAL ) ... and openLDAP - what can possibly go wrong ?

So I haven't installed/used IBM Tivoli Access Manager for e-business ( WebSEAL ) properly since ~2008, although I've worked with a number of clients utilising this secure reverse proxy access management solution.

Last night, I decided to rectify that, and install/configure TAMeB on a VM on my Mac.

Me being me, I decided not to bother with documentation or too many pre-requisites, so I downloaded the software ( plus fixes, taking me to version 6.1.1.8 ), and try and configure it against ... openLDAP. Last time around, I did the right thing and used a "real" user identity management solution, IBM Tivoli Directory Server.

So, after much hacking around, I got to a bit of a blocker.

As part of the installation, one is required to run the following command: -

./install_ammgr -console

to install AND configure TAM.

This, in part, runs the following command: -

/opt/PolicyDirector/sbin/PDMgr_config

This runs for a while and then fails with: -

Unable to verify the management domain location DN in the
LDAP server: (secAuthority=Default).
If the location does not exist on the server, create it,
otherwise specify a different location that does exist.

2014-10-15-21:20:23.563+01:00I----- 0x16B480C9 IRAapi ERROR rgy ira ira_domain.c 1424 0xf77e46c0
HPDRG0201E   Error code 0x22 was received from the LDAP server. Error text: "Invalid DN syntax".


Whist this was obviously an LDAP issue, I wasn't too sure precisely what the root cause was.

Thankfully, some digging about in various internal/external fora gave me these two life-saver commands: -

export LDAP_DEBUG=65535 
export LDAP_DEBUG_FILE=/tmp/ldap_debug_file 

Having run these inside the shell from which I then ran PDMgr_config, I got a nice trace log - /tmp/ldap_debug_file - which contained, in part: -

This made me think, and look for references to secAuthority=Default online, from whence I found: -



both of which made me realise that TAMeB is looking for a particular suffix/object class, which, of course, doesn't exist, by default, in openLDAP.

Now I'm not sure whether I'll continue to hack around to make TAMeB work with openLDAP, or follow the path of least resistance and install ITDS .........

However, it's good to know about that LDAP debug string, as I'm SURE to need it again in the future ....
