Hi Ravee, The MULTIPLE_OWNER support is a vendor-defined feature (meaning, not in OCF Specifications), so the M_O behavior may not be clear if you’re reading the Specifications and looking at the M_O code.
However with M_O compiled out, what you are seeing looks correct: after completing the JustWorks OTM, the /cred Resource should have rowneruuid = <OBT UUID>, which should not be the Nil UUID (all zeroes). Can you explain if there is an issue/concern? Or are you just confirming what you see is expected? Thanks, Nathan From: iotivity-dev-boun...@lists.iotivity.org [mailto:iotivity-dev-boun...@lists.iotivity.org] On Behalf Of Raveendranath Kondrakunta Sent: Tuesday, February 27, 2018 8:31 AM To: a.vol...@samsung.com Cc: iotivity-dev@lists.iotivity.org Subject: Re: [dev] SaveOwnerPSK - Bug or Intentional Thanks Aleksey. Yes, from the Cred data structure, for MULTIPLE_OWNER scenario, there is eownerID. How is it expected to behave, if the stack is not built for MULTIPLE_OWNER support. I've built the stack without MULTIPLE_OWNER support. * Completed Ownership transfer, using just works * OBT is trying to install Owner Credential(OC) using SaveOwnerPSK * The persistent store(oic_svr_db_server.dat and oic_svr_db_client.dat) have Owner Credential (OC) stored in them without rowneruuid all zeros. -Ravee On Tue, Feb 27, 2018 at 8:54 PM, Oleksiy Volkov <a.vol...@samsung.com<mailto:a.vol...@samsung.com>> wrote: Hi Raveendranath, This isn't ownerid, this is eownerID for MULTIPLE_OWNER scenario.

This was generating a Symmetric pair wise key. The ownerid of the credential is set NULL, meaning that rowneruuid is all zeros. Is this intentional or a bug? 802<https://gerrit.iotivity.org/gerrit/gitweb?p=iotivity.git;a=blob;f=resource/csdk/security/provisioning/src/ownershiptransfermanager.c;h=b77e612c1ed7423e62ba8538f98eb8ca86f526fd;hb=HEAD#l802> static OCStackResult SaveOwnerPSK(OCProvisionDev_t *selectedDeviceInfo) 803<https://gerrit.iotivity.org/gerrit/gitweb?p=iotivity.git;a=blob;f=resource/csdk/security/provisioning/src/ownershiptransfermanager.c;h=b77e612c1ed7423e62ba8538f98eb8ca86f526fd;hb=HEAD#l803> { 804<https://gerrit.iotivity.org/gerrit/gitweb?p=iotivity.git;a=blob;f=resource/csdk/security/provisioning/src/ownershiptransfermanager.c;h=b77e612c1ed7423e62ba8538f98eb8ca86f526fd;hb=HEAD#l804> OIC_LOG(DEBUG, TAG, "IN SaveOwnerPSK");
