After updating my phonebook, ldap crashes:

Ftiz!Box can read in the phonebook w/o problems...

...additional info:
I have an ampersand in FN: name. But upload and download works with Fritz!Box and Thunderbird w/o any issue.
This ampersand is also in the vcf VCard file, because name of vcf = FN content.
Seems this is the problem....

Thanks for detailed reporting.
I will check it soon during the next days.

Just checked the issue and made me a contact with an amperstand (&) in it.
Unfortunately I can't reproduce the issue. Probably because my code has changed a lot in between.
But to be sure, can you please check if your server is probably escaping the & character in any way (by exporting/checking the single VCF)? I had a similar issue with an old Nextcloud VCF where the " character got escape in a wrong fashion (\\").

Hi Andreas,

attached you'll find the next beta. You probably like to check the amperstand character issue.
This beta-2 also addresses #25, means: ORG use now index=0 by default and LDAP "department" attribute has also a default config entry.

Hi Jörg,

just tested – same crash as before.

You can create the following vcf for testing (exactly used in this way by Baikal carddav server).


Hans & Peter.vcf




FN:Hans & Peter

N:;Hans & Peter;;;




Hopefully this helps to create the error by your own.

Hi Andreas,

thanks a lot for testing and reporting.

I imported your VCF sample to my nextcloud instance, but it works without any issue, exactly like my test-VCF (with an amperstand) I created before.

So I guessed that it has something to do with special escaping made by Baikal or more likely, because of the vcf file name (with the amperstand).
Unfortunately I didn't found a solution to build such a vcf with nextcloud.

For better debugging possibilities I installed Baikal via "git clone ..." pointed my webserver to it, did the admin- configuration stuff on the web-interface, created a user account (and address book) and imported the "Hans & Peter.vcf" file.
So far so good, but when I try now to point my L2CPBG to the Baikal URL/Addressbook I always get an "Bad status: 405 = Method Not Allowed: The requested method PROPFIND is not allowed for this URL" error.
Really funny that I fail to use my own tool ;-) but I'm very unfamiliar with Baikal as well as Baikal look like a very rudimentary carddav implementation for me.
Do I need to install any kind of Baikal Plugin or similar?
How does your Baikal server URL look within your L2CPBG config?

You’re right. Has nothing to do with content. I changed in Baikal the URI from “&” to “u.” – and it works. So the error is direct related to the vcf name used. In my opinion, this could be also done in nextcloud/owncloud, if you upload a file with an ampersand in filename.

PROPFIND is supported in Baikal.

URL for Baikal, I’m using, is:

Thanks a lot for your help, also the Baikal one ;-)
I had a wrong Rewrite condition in my apache.conf.
After that I was able to reproduce and fix the issue.

I also got it reproduced within Netxcloud (my primary debugging and test environment) after I renamed the VCF directly within Nextcloud's DB (Nextcloud assign own UUID formatted VCF names when importing VCF files).

By the way:
Using "http://<hostname>/dav.php" as L2CPBG Server URL is enough, but by this you're able to use multiple and selective address books in L2CPBG.

Might you take a look @ ticket #28?!
