OTDS – Installation of Replicas fail if the OT Admin password is too long?

For simplicity, in this blog, I will refer to the first OTDS instance as the “Primary” (the synchronization master host, installed with ISREPLICA_TOPOLOGY=0=FALSE) and any additional instances as “Replicas” (installed with ISREPLICA_TOPOLOGY=1=TRUE). Over the past few years, I have installed(…)

Dctm – Another DM_LICENSE_E_INVALID_LICENSE error but caused by JMS this time

At the end of last year, I published a first blog about a DM_LICENSE_E_INVALID_LICENSE error in D2 SSO login through OTDS. The root cause in that previous post was a duplicate user with one lowercase and(…)

Dctm – IDS Source 16.7.5 config.bin crash during execution

Around six months ago, I faced a confusing issue with IDS Source 16.7.5 where the “config.bin” executable always crashed when I tried to run it. The installation of IDS binaries itself completed successfully without any errors. However, the configurator, which(…)

Dctm – Upgrade from 23.4 to 25.4 fails with DM_SERVER_E_SOCKOPT

Since its release in Q4 2025, I have worked on several upgrades from 23.4 to 25.4. The first one I worked on was for a customer using our own custom Documentum images. If you have followed my posts for some(…)

Dctm – Detect and analyze slow SQL queries

Dctm – Managing licenses through OTDS

As you might know, since Documentum 24.4, there is a new requirement to have a valid license assigned to a user in order to log in to Documentum. This is a pretty important change, most likely designed with the X-Plan(…)

Dctm – Incorrect r_object_id reference in OTDS

I recently faced another pretty interesting case with an incorrect r_object_id reference in OTDS. In a non-production (dev) Active Directory (Azure EntraID) that is used as source of truth for the users/groups, it looked like there was an account which(…)

Dctm – MFA & non-MFA within OTDS based on target Applications

In OpenText Directory Services (OTDS), you have multiple ways to handle two-factor authentication (2FA) or multi-factor authentication (MFA). As a quick reminder, 2FA is simply the fact that you need to prove your identity in 2 different ways (e.g. a(…)

Dctm – OTDS SSO with sAMAccountName AD/LDAP attribute and Azure

The OpenText Directory Services (OTDS) is a pretty interesting piece of software, and it works quite well out-of-the-box. If you are starting to use the OTDS from scratch (when you have nothing internally), then there isn’t much problem, you can(…)

Dctm – D2 SSO through OTDS fails with DM_LICENSE_E_INVALID_LICENSE

After doing some more upgrades from Documentum 20.2 to 23.4, including D2, I faced a funny error about invalid licenses (DM_LICENSE_E_INVALID_LICENSE) while trying to login to D2 through OTDS SSO. That’s interesting because there is no license management for Documentum(…)
