[Kolab-devel] Kolab 3.5 Development on Centos 7.2

Hi list,
I tried to upgrade to Kolab 3.5 Development on Centos 7.2.

First there was a conflict with installed php-mysql and to be installed 
php-mysqlnd.
     rpm --nodeps -e php-mysql
     yum install php-mysqlnd
fixed this.

yum install roundcubemal-plugin-enigma
needs additionally at least php-pear-crypt-gpg

Activesync does not work:
[31-Jan-2016 08:01:04 Europe/Berlin] PHP Fatal error:  Call to protected 
method rcube_imap_generic::strToTime() from context 
'kolab_sync_data_email' in 
/usr/share/kolab-syncroton/lib/kolab_sync_data_email.php on line 140
Making the function public fixed Activesync.

Chwala/Kolab-files does not work
This is mysterious: First, the default in kolab_files.inc.php does not 
work, the only working config is
$config['kolab_files_url'] = '/chwala';
With this I get no errors at all, anywhere (chwala-logs, httpd-logs, 
roundcube-logs, kolab-logs)
::1 - [email protected] [31/Jan/2016:08:38:11 +0100] "GET 
/chwala/api/?method=authenticate&version=2 HTTP/1.1" 200 123 "-" 
"Mozilla/5.0 (Windows NT 10.0; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0"
But logging in on the /chwala URL gives "user name or password wrong" 
and in Roundcube the Files-Page displays, but there are no files and 
everything is non-functional. Troy Carpenter reported similar issues 
with seafile integration.

Kind regards,
Thomas
