[Samba] Users being deleted from Domain Users group on Samba BDC during vampire process of migration

Tue Nov 23 18:52:16 GMT 2004

I think I'm having a problem during the vampire process.  Would someone
tell me why my domain users are being deleted from the Domain Users group
after they are created?

First, the accounts are being created normally...

Creating account: marshah
Creating account: marshab
Creating account: johnp
.
.
.
Creating account: ronniem
Creating account: bobbyr
Creating account: robertk
Creating account: g4400$
Creating account: INFI2292-80$
Creating account: PAP-E06EFL2FLCA$
Creating account: G830-78$
Creating account: COL190GPCTAB-62$
Creating account: PERIA30-63$
Creating account: ROM010IA30-71$
Creating account: DEK480IA30-73$
Group members of Domain Admins:
charliebrown,faxserver,joeblow(primary),vbe(primary),snoopy(primary),epo,xerox,
Group members of Domain Users: PRIMARY$(primary),CONSDEV
$(primary),marshah(primary),marshab(primary),johnp(primary) . . . <snip>
rajg(primary),FIEGATEWAY450-5$(primary),MAC120I2652-8
$(primary),FISGE2000D-2$(primary),DISGE2000D-1$(primary),ADA440GPCTAB-6
$(primary),CJRG450ROG-29$(primary),DAL230GPCTAB-21
$(primary),THO070GPCTAB-65$(primary),CAN300GPCTAB-5
$(primary),ADA440GPCTAB-75$(primary),THO070GPCTAB-7
$(primary),CAN300GPCTAB-4$(primary),DOU400GPCTAB-25
$(primary),CAR540GPCTAB-8$(primary),LAG310GPCTAB-5$(primary),ELL560GPCTAB-2
$(primary),LAG310GPCTAB-12$(primary),ELL560GPCTAB-18
$(primary),LAG310GPCTAB-2$(primary),ELL560GPCTAB-4$(primary),CON360GPCTAB-2
$(primary),LAG310GPTAB-15$(primary),INFGFE2000D-100
$(primary),LAG310GPCTAB-6$(primary),DAH590GPCTAB-6$(primary)
.
.
.
<snip>

Then the users are being deleted . . .

deleting user marshah from group Domain Users
deleting user marshab from group Domain Users
deleting user johnp from group Domain Users
.
.
.
deleting user joyceb from group Domain Users
deleting user lyndae from group Domain Users
deleting user janices from group Domain Users
deleting user mredding from group Domain Users
deleting user darylb from group Domain Users
deleting user deborahm from group Domain Users
deleting user tammyc from group Domain Users
deleting user jeanettb from group Domain Users
deleting user dessiep from group Domain Users
deleting user jennifej from group Domain Users

The users with "(primary)" attached to their name are being deleted.  As
you can see, the Domain Admins group no longer includes jonathanb, ninos or
vbe.

sd1:~# getent group | grep "Domain Admins"
Domain Admins:x:512:charliebrown,faxserver,epo,xerox

There were several hundred domain users but after the migration there are
only a few.
