zimbra_samba cannot read samba domain

[mugo]

Hi everyone.
After successfully deploying the zimbra samba extension, it cannot correctly read my current domain information and gives the message

JavaScript error encountered in method ZaOverviewPanelController.prototype._overviewTreeL istener message: entry has no properties fileName: https://localhost:7071/service/zimle...v=080522110555 lineNumber: 46 stack: (undefined)@https://localhost:7071/service/zimlet/zimbra_samba/ZaSambaDomainController.js?v=080522110555:46 ([object Object])@https://...

The extension sees that there is a domain but all there is under domains is "@"

Here is the contents of the last few lines of mailbox.log.
