Running Red Hat Linux (standalone and/or in a zLinux environment), you will not be able to assign a user to the defined maximum of 32 group memberships.
There is a limit to the number of groups of which a user can be a member. In most cases, users can be members of up to 32 groups, as defined in /etc/group but the Tectia server does not recognize that many groups when the Operating System is Red Hat Linux (zLinux).
Group membership, in the case of Red Hat Linux (zLinux) is a limitation of the OS. RedHat Linux allows a maximum group membership of 32, 16 if using an NFS mounted filesystem.
You will have to use the Tectia config file, /etc/ssh2/ssh-server-config.xml, to mange the access of each user if you are using Red Hat Linux and/or zLinux (Red Hat).
