When attempting to configure a Symantec Messaging Gateway 10.6.1 Directory Integration Data Source the configuration changes are not saved and you see an invalid credentials error.
Authentication to LDAP server unsuccessful. Invalid bind credentials. DDS error code: 800206
This issue has been addressed with the Messaging Gateway 10.6.2 release.
Please see the Messaging Gateway Administration Guide for detailed instructions on how to update the SMG software.
If a Data Source change is needed, a workaround would be to remove an existing data source and create a new one with the modifications in place.
Same error will be observed if you try to run test queries after the initial configuration is done. You have to follow the workaround to delete the source and then try to create it again and test all the queries during initial setup and don't run any further test once it is saved.
