[Samba] net groupmap displays multiples

[Chris Smith]

A "net groupmap list" show 2 each of "Domain Admins" and "Domain Guests" as 
marked below with ** and *** respectively.

System Operators (S-1-5-32-549) -> -1
Replicators (S-1-5-32-552) -> -1
Guests (S-1-5-32-546) -> -1
Power Users (S-1-5-32-547) -> -1
Print Operators (S-1-5-32-550) -> -1
Administrators (S-1-5-32-544) -> -1
**Domain Admins (S-1-5-21-1068423669-2868761170-579274183-512) -> -1
Account Operators (S-1-5-32-548) -> -1
***Domain Guests (S-1-5-21-1068423669-2868761170-579274183-514) -> -1
Domain Users (S-1-5-21-1068423669-2868761170-579274183-513) -> users
**Domain Admins (S-1-5-21-2884117546-2866258145-1073336595-512) -> -1
Backup Operators (S-1-5-32-551) -> -1
Users (S-1-5-32-545) -> -1
***Domain Guests (S-1-5-21-2884117546-2866258145-1073336595-514) -> -1

A "net groupmap delete ntgroup="Domain Admins"" looks like it works: 
"Sucessfully removed Domain Admins from the mapping db" but yet the multiples 
remain. Is this normal and if not what can or should be done.

Thanks.
