WebDAV locking issues

Trying to create a folder on my WebDAV share, using Cyberduck, but couldn’t:

The logs:

# tail -f /var/log/httpd/ssl_error_log

Where is the lock database?

# vi /etc/httpd/conf.d/webdav.conf

/var/lib/dav/lockdb


Turns out, that directory doesn’t exist, that’s a simple fix:

[root@server ~]# namei -l /var/lib/dav/lockdb

f: /var/lib/dav/lockdb

dr-xr-xr-x root root /

drwxr-xr-x root root var

drwxr-xr-x root root lib

                     dav - No such file or directory

[root@server ~]# mkdir -p /var/lib/dav/

[root@server ~]# chown apache:files /var/lib/dav/

[root@server ~]# namei -l /var/lib/dav/lockdb

f: /var/lib/dav/lockdb

dr-xr-xr-x root   root  /

drwxr-xr-x root   root  var

drwxr-xr-x root   root  lib

drwxr-xr-x apache files dav

                        lockdb - No such file or directory


Hopefully.

# systemctl restart httpd


And hey, what do you know, now it works:

192.168.1.1 - username [02/Feb/2026:12:25:55 -0800] "MKCOL /shares/documents/Law%20Firm/ HTTP/1.1" 201 247

192.168.1.1 - username [02/Feb/2026:12:25:55 -0800] "PROPFIND /shares/documents/Law%20Firm/ HTTP/1.1" 207 858


# namei -l /var/lib/dav/lockdb

f: /var/lib/dav/lockdb

dr-xr-xr-x root   root  /

drwxr-xr-x root   root  var

drwxr-xr-x root   root  lib

drwxr-xr-x apache files dav

-rwxr-xr-x apache files lockdb
