Hi, We are having a problem with Samba 3.0.13 winbind on Sparc Solaris 8 NT4 domain. The following is appearing during our overnight backup jobs and looks like winbind cannot map a unix uid to a windows SID. Samba itself works and users are able to see and use the share. Wbinfo -u -g -t all work I have winbind in nsswitch.conf passwd: files winbind group: files winbind The output of log.winbindd is as follows Copyright The Samba Team 2000-2004 [2005/05/17 20:41:10, 1] nsswitch/winbindd.c:main(864) winbindd version 3.0.13 started. Copyright The Samba Team 2000-2004 [2005/05/18 01:44:20, 1] nsswitch/winbindd_user.c:winbindd_getpwuid(238) could not convert uid 10259 to SID [2005/05/18 01:48:08, 1] nsswitch/winbindd_user.c:winbindd_getpwuid(238) could not convert uid 10259 to SID [2005/05/18 07:10:03, 1] nsswitch/winbindd.c:main(864) winbindd version 3.0.13 started. Copyright The Samba Team 2000-2004 The problem also occurs when running ls -l from the UNIX prompt which hangs on the samba share directory ls -ln works. Any help appreciated. Thank You Graeme
