Is there any generic way to detect user's existence over RHEL and
Solaris? I want to write a shell script to do so. Thanks.

Leaving issue of non-atomicness aside, you could use the id command
for that. 'id <username>' will return a non-zero exit status the user
does not exist. This is not the only reason which may cause it to
fail, but presumably, the most 'common' one, and it should be able to
deal with things like NIS maps.
