Don't think the user's uid/gid matter.  Make sure you have
both the short machine name and the FQDN in the .rhosts file.
For instance, coming from a SUN machine (carmel.sclab.tarantella.com)
to a OSR5 machine (jupiter.beyond.tarantella.com), the .rhost file:

carmel
carmel.sclab.tarantella.com

works (no password prompt), while an .rhost file with just "carmel" 
doesn't.  I've always included both forms of machine names in my
.rhost files, cause sometimes you need them :-)

oh, my uid/gid on the two systems is completely different.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
