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 – 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(…)
