Resolution

All the issues are caused by corrupted or invalid user credentials used by Citrix IMA to connect to the database. To fix the issue, use DSMAINT utility to update the configuration parameters used by Citrix to connect to the data store.

The command syntax is:

DSMAINT CONFIG /user:domain\user_name /pwd:password

Replace the domain, user_name and password with the valid values. For example:

DSMAINT CONFIG /user:TECHJOURNEY\Administrator /pwd:DomainAdminPassword

You should see something like below that indicates everything is successful:

Calling IMASetPSPassword
Attempting to connect to the data store with new configuration settings.
Successfully connected to the data store.
Configuration successfully changed.
Please restart the IMA Service for changes to take effect.

DSMAINT CONFIG

After running the command, restart IMA Service (Citrix Independent Management Architecture) for changes to take effect.

Restart Citrix IMA Service
Restart Citrix IMA Service
Restart also the related Citrix services if prompted.

Then, the Citrix AppCenter or Citrix Delivery Services Console will be able to connect to data store for discovery to be successful.
