[vishesh kumar]

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
