Somehow that doesn't sound quite right. Does anybody know for certain?

Making some assumptions on your question....

Usernames are associated with user IDs (UIDs). UIDs are numbers from zero to 65534. Check out the /etc/passwd file. Every username is assigned a number. i.e
root UID 0 and nobody is 65534. AFAIK it depends on the distribution but normal users typically start at 500.

If your asking about how many concurent connections on a server then that would be determined by the application and server hardware.

Thanks for the replies..

for clarification, it's not so much concurrent connections. We are currently have a server that receives data from our clients for a data warehouse. Unfortunately our current setup requires us to have each client exist as a user on the server and we were just wondering if/when we would run into a wall with that.

Quote:
Version 2.6 - current (December 17, 2003 to the present)
.....
# Increased the maximum number of users and groups each from 65,536 to over 4 billion.
# Increased the maximum number of process ids from 32,768 to over 1 billion.
