pure-ftpd: unable to switch capabilities

[Tomasz Olszewski]

Witam!

Przy próbie uruchomienia pure-ftpd dostaję komunikat:

421 Unable to switch capabilities : Operation not permitted

Rzeczywiście, strace pokazuje, że:

capset(0x19980330, 0, {CAP_CHOWN|CAP_DAC_READ_SEARCH|CAP_SETGID|CAP_SETUID|
CAP_NET_BIND_SERVICE|CAP_NET_ADMIN|CAP_SYS_CHROOT|CAP_SYS_NICE, CAP_CHOWN|
CAP_DAC_READ_SEARCH|CAP_SETGID|CAP_SETUID|CAP_NET_BIND_SERVICE|CAP_NET_ADMIN|
CAP_SYS_CHROOT|CAP_SYS_NICE, }) = -1 EPERM (Operation not permitted)
rt_sigprocmask(SIG_BLOCK, ~[RTMIN RT_1], [], 8) = 0
fstat64(1, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 0), ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 
0x4068f000
write(1, "421 Unable to switch capabilitie"..., 61421 Unable to switch 
capabilities : Operation not permitted
) = 61

Ktoś wie, co z tym zrobić? Zdarzenie ma miejsce na aktualnym Ac, 
pure-ftpd-1.0.20-5.
