r24388: - ACL retrieval provided incomplete information because the buffer pointer was
incremented too far in some circumstances. In these cases, only the first of multiple concatenated strings would be seen. - Working on bug 4649 pertaining to delete an ACL, this fixes the reported crash. It appears to have been an incomplete switchover from malloc to talloc, as the memory was still being freed with SAFE_FREE. Deleting ACLs still doesn't work. Although a valid request is sent to the server and a SUCCESS response is returned, the method that's used in libsmbclient for deleting ACLs seems to be incorrect. In looking at the samba4 torture tests, it appears that we should be turning on the INHERIT flag if we want to delete the ACL. (I could use some assistance on the proper flags to send, from anyone familiar with this stuff.) - Apply patch from SATOH Fumiyasu to fix bug 4750. smbc_telldir_ctx() was not returning a value useful to smbc_lseekdir_ctx(). Derrell (This used to be commit 2ac502e29bd8390252fe4ae8344faab49ca01ff5)
