samba share

[EU-Admins-UNIX]

HI

We have a samba share mapped to users workstations.  The group of users can write the the level of the share and a particular directory below, but only one of them cannot write to the directory below:

the share is

/dir1/dir2 (all can write to this)

the subdir is

/dir1/dir2/subdir (all bar 1 can write to this)

All group membership on the HP-UX 11.31 of the users is the same.

The Windows team have looked at their AD accounts, all seem OK there too.

Where else should I be looking?

Regards

Tariq
