Mike,

using the current set of stable pear packages of Horde, I'm also not 
able to reproduce it.

I recommend to close the bug. Thanks for your help.

I'll check that, but I'm on the road for four days. I'll come back to 
this issue on Tuesday or Wednesday.

Can you see what $passwords is equal to right before the for loop?

When it did break for me, it was an unencrypted binary string when the 
original $password array contained a single entry in element (int)0. 
If the entry was "moved" to element '1', it worked but I can't get it 
to break again. It's always returned as an array now.

....and now I can't reproduce it at all :(

Thanks for the update

There seems to be some issue with decompressing certain arrays with 
numeric keys. I've been able to reproduce it on one machine using PHP 
5.6, but not on my dev machine running php 7.

Still investigating.

The real question is why is a non-array value returned from 
$session->get when the TYPE_ARRAY mask is passed? Perhaps it's an 
issue in Horde_Session when a value is saved with the ENCRYPT mask but 
retrieved with the TYPE_ARRAY mask.

Gollem Auth (gollem/lib/Auth.php ~line 340) throws warnings: "PHP 
ERROR: Invalid argument supplied for foreach()"

Since the causing function _getBackends() is invoked several times, it 
pollutes the logfile.

In the mentioned function, the passwords are retrieved and iterated 
via foreach. However, if only a singlr password is returned, PHP 
complains that it is no array.

I propose to insert an cast into array to have a defined type 
presented to foreach() to correct the problem.


The fixed function should be like this:


gollem/lib/Auth.php:
     /**
      * Return stored backend list.
      *
      * @return array  Backend configuration list.
      */
     protected static function _getBackends()
     {
         global $session;

         if (($backends = $session->get('gollem', 'backends', 
$session::TYPE_ARRAY)) &&
             ($passwords = $session->get('gollem', 
'backends_password', $session::TYPE_ARRAY))) {
             foreach ( (array) $passwords as $key => $val) {
                 $backends[$key]['params']['password'] = $val;
             }
         }

         return $backends;
     }


Thanks,
Torben
