[imp] Problem logging into Gmail Imap

[JLA ENTERPRISES DIRECT]

Hi there,

Fresh installation of Horde Groupware 1.1.1 with IMP H3 4.2 and dimp h3 1.0
running on IIS6 all with no problems.  Tested IMP with AOL imap and
functioned as expected with no problems

Then went to test with Gmail imap and receive the following error when
attempting to login - 

Error connecting to IMAP server: [0] The operation completed successfully. .

IMAP is enabled in Gmail settings.  IMAP functions with outlook.  Also ran
IMP test script and was successful in receiving settings for the Gmail IMAP.

Any help appreciated.
