In wbclient.c the call that causes signal 11 is the call to initgroups in the winbind_initgroups function. -----Original Message----- First off, we are forced to using said versions and NIS+, so no flaming on those issues please. Also, the samba version we recieved was forced upon us and we are not allowed to recompile, however in a test environment we've compiled both with and without NIS+ support and the same errors are generated. When removing nisplus from group entry of nsswitch.conf samba works fine. With nisplus listed in nsswitch.conf group entry, the forked smbd process dies when attemping to connect with either a Windows machine or smbclient. Here is the error from the smbclient connection attempt: session setup failed: Call returned zero bytes (EOF) (truss output) incurred fault #6, FLTBOUNDS %pc = 0xEF5DA2B0 siginfo: SIGSEGV SEGV_MAPERR addr=0x0084D62C Recieved signal #11, SIGSEGV [caught] siginfo: SIGSEGV SEGV_MAPERR addr=0x0084D62C from debug level 10 smbd/sec_ctx.c:set_sec_ctx(329) setting sec ctx (0, 0) - sec_ctx_stack_ndx =1 lib/fault.c:fault_report(38) smb.conf setup [global] workgroup = workgroup security = SERVER encrypt passwords = Yes password server = pserver Thanks for any helpful information. Preferred solution is to be able to use nisplus listed in groups entry of nsswitch.conf.
