Hello, I'm facing a bug with winbind. If I request groups for particular domain user, winbind cache gets corrupted. My winbind version is 4.1.12-23.el7_1 (Centos 7.1, x86_64). 1) this is correct UID to SID mapping: wbinfo -U 100152 S-1-5-21-3451901064-902568176-4053310204-180212 2) I request groups info for a user: id -G -n 209459 [reply with 33 groups] 3) I request UID to SID mapping
