Ok, I tested 10.0.1 with NS but used the zip (non RPM) provided by Nextcloud. Installation was straightfoward (uncompressed into a new directory within the default www directory, created a new mysql database and user, then installed Nextcloud).
LDAP integration was falirly simple (duplicate the configuration from the previous NS based installation.)
Now that there is an RPM availble, Tomorrow I will remove the existing versions and install the RPM version.
I am intending to test both Webdavs (caldav, cardav) and file management features, I am not intending to test the client software (prefer to use dav to connect the server shares)
As far as I am concerned, The new version of Nextcloud should be fairly straightforward to integrate with NS (as stated above I will install the RPM version and see if I can use the existing NS NextCloud configuration files)
Also I remember reading somewhere within this forum that some people have mentioned that they have been using Samba with NextCloud / OwnCloud file management tools, I would suggest that this maybe a bad idea due to Nextcloud need to synchronize file information (ie. file tags and description information) to the mysql database and if using Samba to the file server then this information will not be updated with the database, therefore the files may not be displayed in the Nextcloud interface or when using webdav / desktop client software).
