IS_MEMBER giving wrong results

[sunila7]

Hi,

I am using Is_member function to determine wether a user has permissions to a particular role.

I have a role called Adminstrator and a user is a member of that role.

when i give the System Admin and Security Admin roles to this user, is_member returns a zero for Administrator role.

if i remove this 2 (System Admin and Security Admin ) roles for that login, it returns the right values i.e 1.

Any suggestions on this will be greatly appreciated

Thanks
Sunil
