Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

Symptoms:

• after changing an attribute, in "Sync Settings > Mapped Attributes" for the configured directory, when trying to save the directory the below banner is seen
  
• In /opt/vmware/horizon/workspace/logs/connector.log the following IndexOutOfBoundsException can be seen

Environment

VMware Identity Manager 3.3.7

Resolution

The configured account for the directory sync has no access to read from the newly configured property.

Please review the permissions of the account and allow access to read from this property.

Additional Information

Another possible reason for the error "Connector communication failed because of invalid data:  Index: 0, Size: 0" is if the configured account has multiple emails assigned in AD.

Accounts with multiple emails in the info field of AD will only work if the email addresses are separated by a ', ' and not a line break.
