Hi, It is a question of increasing the number of groups to which a Linux user can belong. By default, this number is 32 (cf /usr/include/linux/limits.h or in the sources of the kernel /usr/src/linux/include/linux/limits.h). The distribution is Debian 2.2 (potato), the kernel is the 2.2.19.
By modifying the following line in these headers: # define NGROUPS_MAX 32 in: # define NGROUPS_MAX 64 and by compiling the kernel, this one must be able to support the increase. One needs then recompile some packages: - shellutils - login - passwd which contain the utilities for managing users and groups. After their installation, some problems remains: usermod works correctly and wants to make well belong a user in 64 groups, but id returns only the first 32 groups to which belongs the user. IMO, the sources of id do not seem in question. The goal of the operation is to increase the number of VirtualHosts managed by Apache (a VHost = a User/Group couple). In detail: - Apache is started by a user (for Debian, www-data); - scripts PHP are also started by this user; - to preserve each VHost environment, only user and his/her group can go the base directory; - So that scripts PHP are executed correctly in the environment of each VHost, it is necessary that the user www-data belongs to the user group who possess each VHost. So, here are beginning my problems... Do I need to recompile Apache? If someone has an idea or eventually another solution? How is it managed on ISP servers?
