Nextcloud : 19.0.3 Operating system and version : Ubuntu 20.04 Apache version : 2.4.41 PHP version: 7.4.3 Thunderbird: 68.10.0 Lighing: 68.10.0 Hello, I used Nextcloud with Ubuntu 16.04 and Thunderbird with Lightning and the CalDAV-calendar. Now I switched to an new Server with Ubuntu 20.04 and Thunderbird is no longer saving my password in his password manager, debug info: `Error: Can't add a login without a httpRealm or formSubmitURL.​` Any Ideas?

Please EXPLAIN IN DETAIL how you try to add a calendar link to Thunderbird, otherwise it will be difficult to narrow down the problem. Have you set “ **calendar.network.multirealm = true** ” in the Thunderbird configuration editor? ---

Hello, I used the recommended way, exactly: [https://docs.nextcloud.com/server/19/user\_manual/pim/sync\_thunderbird.html#recommended-method](https://docs.nextcloud.com/server/19/user_manual/pim/sync_thunderbird.html#recommended-method) But I also tried a few other methods later with new Thunderbird profile… Your workaround with “ **calendar.network.multirealm = true** ” is working, thanks a lot. Where did you get this information from? Other thing is, I think this is only a workaround, and the problem is still this missing header information. This is an old Nextcloud installation, first installed five years ago and updated since then. I dont have this problem with a new, fresh installed Nextcloud instance or other DAV-Servers, like Baikal. While I can live with your tip, it would be nice to find the reason 🙂 Thanks ---

> [@zentrix](#): > > Your workaround with “ **calendar.network.multirealm = true** ” is working, thanks a lot. Where did you get this information from? This is not a workaround but a known Thunderbird parameter to handle multiple accounts on the same server domain in parallel. By default Thunderbird can only handle one set of credentials for a server address domain. By setting this parameter, it accepts multiple credentials of multiple accounts. ---

Thanks for your reply. It is only one account, I use it since five years without this parameter. So I guess this it not the reason for my problem. ---

Each calendar is counted separately, independent if it is owned by the same user or not. I don’t remember with which Thunderbird versions this parameter has been introduced but based on my experience it’s essential to get a reliable connection to the server established. If you search the internet, you will find many matches covering this issue. ---

Ok, so I have tried now to disabled **multirealm** parameter (set so false), disabled all calendars and adressbooks and enable only one calendar. Thunderbird is no longer asking for password, fine. Then I enabled again the other calendars and adressbooks, it is still not asking for passwords now. Then I deleted all stored passwords, and after restarting Thunderbird, I only get asked for one password… no longer get asked for every calendar, still with **multirealm** disabled. Strange. I changed one thing a few hours ago: **Settings - Theming - Name** , and then it was asking for password for every calendar after restarting. So I try now with new Thunderbird profile - add one calendar ,password is saved ! Second calendar, like expected, it don’t ask for any password. So, to verify this is a **Settings - Theming - Name** problem, I tried to remove the name, message: Name cannot be empty", but it seems to be saved empty anyway. Ok, new Thunderbird profile, add one calendar ,password is **not** saved ! I also tried this two times with only Lightning and two times with the AddOn TBSync, sale results. In conclusion I can say: 1. You **don’t** have to use **calendar.network.multirealm = true** , not even for multiple calendars from one user. 2. You **don’t** have to use TBSync (but then you need something else for adressbooks), DAV-calendars are working with Lightning only 3. You **have to** set a Name in **Settings - Theming - Name** ---

Hello, @zentrix where is this **Settings - Theming - Name** configuration item ? I think I have the same problem as yours and I’d like to try your solution but I can’t find this setting 😕 Thanks ---

Actually setting **calendar.network.multirealm = true** solved this issue for me too ! Thanks ---

I love you, I have this issue since several years, I tried this method, and it perfectly worked… A no-named nextcloud can’t be stored in Thunderbird database for agendas… Thanks a lot, you’re my life savior ! ---

Another two years later, I stumbled across the same issue. Setting a name in theming settings is still the correct solution, in case you see the “missing httpRealm” error in Thunderbird console. The realm is actually a mandatory part of the basic HTTP authentication header: [WWW-Authenticate - HTTP | MDN](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/WWW-Authenticate#basic) Not sure what Nextcloud sends in case the name was not set, probably an empty string. Surprising that this is not causing a lot more issues. I’ll see if I can open a PR to have a default realm, or a default name (resulting in a realm) set. “Nextcloud” should do. EDIT: PR up: [fix(dav): fallback realm for HTTP authentication by MichaIng · Pull Request #42459 · nextcloud/server · GitHub](https://github.com/nextcloud/server/pull/42459) ---
