samba - Nov 2008 - smbd process list

Dear all
My server running samba 3.0.28 on RHEL 5.2

command 'ps -aux | grep smbd' list running process in following format

root     29334  0.0  0.1  15748  4384 ?        S    13:41   0:03 smbd -D
16777231 29413  0.0  0.0  15712  3880 ?        S    13:42   0:00 smbd -D
ABP\anil 29414  0.0  0.0  15588  4076 ?        S    13:42   0:00 smbd -D
16777291 29440  0.0  0.1  15992  4292 ?        S    13:43   0:00 smbd -D
16777317 30281  0.0  0.0  15768  4040 ?        S    13:59   0:00 smbd -D
16777242 30475  0.0  0.0  15592  3896 ?        S    14:03   0:00 smbd -D

in first column, some process display root, some display uid number of user
and some display name of user.
I eager to know why smbd process run under diffrent users.

thanks

For normal operations smbd switches into the authenticated
user context. From time to time, smbd needs to perform tasks
that can only be done as root, so it switches back. File
system access will always be done as user.

Hi,

This thing has run in my head either but I forgot to email the forum. Thank
you for throwing this out into the forum Vishes and thanx (again) to Volker
for the explanation.

Best regards,
