Some valuable features in this product are: webSEAL policy, proxy servers, LDAP server (IBM TDS).
The modularity with which each component may run on a different host is valuable. In addition, multiple instances per component might be installed with load balancers. It provides good scalability and reliability, not to mention the overall availability of the service.
The entire security of the intranet and internet web applications has been covered by the TAM environment.
It happened from time to time, that is, after a long period without restart, the TDS/LDAP instances crashed and remained in a hanging state. A restart did solve the issue but the support was not able to find the cause, despite the fact that the latest fix pack was installed for TDS v6.3.
A similar issue came up when LDAP requests did cause performance issues on TDS or caused the TDS to crash.
As information on fixes and issues related to ITDS are publicly available, let me point you to the respective site:
You may notice, there are several issues listed, which lead to a crash.
Not sure, which one is/was ours, but please notice that TAM/SAM requires multiple software bundles to be installed (like GSKit, Java SDK, WAS, DB2) – each of them having issues.
I have used this solution for five years.
We experienced crashing of LDAP with some specific queries and it affected performance of the TDS proxy.
It is scalable via load balancers but there are some issues with sync while using several LDAP trees.
I would give the technical support a 8/10 rating. Sometimes, there are long running support tickets (for 6-8 months) and that is unacceptable from the customer's point of view.
We were not using any other solution before. We were partially using Apache reverse proxy along with LDAP.
The setup is complex. Without training and prior knowledge, it is hard to get a working environment.
As far as I know, the later versions of TAM (renamed to SAM), are working as appliances and with that, no experience is needed. My advice is to be careful and think twice.
