We've had Samba running (16p9, 16p11, 17p1) running on Solaris2.5.1 for quite some time now. It works just fine. We have it running on 2.5 and 2.5.1 machines (mostly the former now, as we finish the upgrades - soon 2.6 *sigh*) I've never seen that problem. Is it possible you used different compile options? Have you tried enabling/disabling FAST_SHARE_MODES? We use -DSUNOS5 -DSHADOW_PWD -DNETGROUP -DNO_STRFTIME -DFAST_SHARE_MODES -DUFC_CRYPT Doug Hughes Engineering Network Services doug@eng.auburn.edu Auburn University
