In our login script I want to add part where all users (approximately 800) will access INI file at the same time and read specific data from it. Will this cause any problem?

The ini file will be like:
[Jhoanxm]
BadgNum=80922
[Mikalbn]
BadgNum=80514
[Sungyxc]
BadgNum=534291

The script will get the user id when he logged on and then access the ini file on the server and extract his BadgNum after it match his user id with the same one in the ini file.

Thank you.
