When configured to look up names with winbind (3.0.2a-1/sarge), postmaster
crashes with the following:
2004-05-14 14:50:14 [8725] LOG: could not create IPv6 socket: Address family
not supported by protocol
2004-05-14 14:50:14 [8725] LOG: authentication file token too long, skipping:
"Â.Ãñ
Segmentation fault
--------------------
... the nsswitch.conf that goes with the above contains:
hosts: wins files dns
However if I change the name lookup order to:
hosts: files dns wins
pg starts up normally and the authentication file token error disappears.
(The IPV6 error remains.)
I tried to get a stack trace; unfortunately the stack is corrupted but this
much (truncated) looks for real:
...
#8 0x40ecb020 in ?? () from /lib/libnss_wins.so.2
...
#35 0x4028efce in __errno_location () from /lib/libc.so.6
Winbind name lookup works fine normally, still I wouldn't be too much surprised
if this was in fact a winbind bug.
