32 bit UIDs on 2.4.14

32 bit UIDs on 2.4.14

[jose]

 Hi.

  What is the trick to get more than 2^16 uids working on all services??

  I'm using kernel 2.4.14, libc6 compiled with 2.4.7 headers, lib(pam|nss)-ldap
  openldap, wu-imap, cuci-pop, samba, telnet, ssh, Debian Potato.

  'id' and 'getent passwd high-uid-user' both return the right uid (which 
is stored on the ldap system), but 'ls -l' truncates the uid if it's higher than
65536 (say for uid  80000, it reports  14464), and sshd, telnetd and imapd deny
logins because setuid() invalidates a >16 bit interger as argument.

   What should I recompile??  is there a moderately easy workaround??



  Thanks



   José

That patch is in the 2.4.13-ac7 don't use -ac8.

It's probably somewhere else, but I don't know who origionally submited the
patch to Alan.

2.4.x kernel
Glibc 2.2
Up to date pam modules
ext2/ext3 file system

patches needed for quotas

reiserfs also works, for 32 bit uids
