Comment 11 Marcus Meissner 2017-08-28 08:35:16 UTC
can you also include in sles11 sp4?
Comment 15 Lidong Zhong 2017-09-04 06:55:59 UTC
Marcus, an L3 incident has already been created for bsc#1056470. Since there
is big change between sles11sp4 and sles12sp2 for openvpn, I have to wait for
Nirmoy's patch and provide the PTF then.
Comment 17 Swamp Workflow Management 2017-10-24 13:08:02 UTC
