Incorrectly converted AD objectGUID

Hi oCIS-Team,
oCIS is incorrectly converting an Active Directory objectGUID.

Raw data: xPYr6y1Rf0SKoM8kmfaYDw==
oCIS: c4f62beb-2d51-7f44-8aa0-cf2499f6980f
Apache Directory Studio: {eb2bf6c4-512d-447f-8aa0-cf2499f6980f}

$ echo "xPYr6y1Rf0SKoM8kmfaYDw==" |base64 -d -i |xxd
00000000: c4f6 2beb 2d51 7f44 8aa0 cf24 99f6 980f ..+.-Q.D...$....
