Thanks for digging into this. And for pointing out where I was wrong. The trimming for CardDAV export is done in function tovCard(...) , case '__tags': https://github.com/horde/turba/blob/master/lib/Driver.php#L1818 leading to https://github.com/horde/Core/blob/master/lib/Horde/Core/Tagger.php#L89 I was seeing the misbehavior with a Debian Jessie installation (which is oldoldstable now), where case '__tags': is not calling Turba_Tagger::split() but doing a simple explode(',', $val) instead. And unfortunately I thought the error is caused by synchronizeTags(), which hasn't changed much since then. So this was fixed ages ago, for Debian since Stretch/9 , as I see now. Sorry for stealing your time, Michael. ...and I can't reproduce this using the 'Card Book' add on to Thunderbird as described in the ticket. My tags are being correctly trimmed as they are synchronized. Please provide a step-by-step way of reproducing this.

Yes, we store it with a comma-space separator, but only internally in Turba. When the Turba_Object is converted to a vCard, this property is split and trimmed in Turba_Tagger::split(); I'll have to trace the code after I get a Thunderbird install going to see where this is(not) happening. [Show Quoted Text - 24 lines][Hide Quoted Text] When syncing address book entry via CardDAV Horde is sending the CATEGORIES property with wrong separation. Horde internally uses categories as tags (or vice versa). RFC is postulating for CATEGORIES property value: "One or more text values separated by a COMMA character" https://tools.ietf.org/html/rfc6350#section-6.7.1 Horde separates by a comma and a space character. This misbeavior is coming from function synchronizeTags(array $tags) in turba/lib/Object.php ... $this->setValue('__tags', implode(', ', $tags)); ... https://github.com/horde/turba/blob/master/lib/Object.php#L313 Some CardDAV clients , for example Thunderbird plugin CardBook, adding the additional space char to the name of the category . As CardBook is using categories for grouping cards, this leads to lots of confusion. Looking forward to seeing this fixed.
