If so, you made your system files inconsistent with the RPM database (bad for integrity checking and for further updates of the system). Also, we do not use some of the programs that are a part of the shadow suite. We use other implementations, coming from other packages. In particular, the passwd(1) command on Owl comes from SimplePAMApps, not from the shadow suite. You've essentially overwritten it with the shadow suite implementation. :-( > Right now all > seems to work, but when I execut i.e. passwd there's such output: > > configuration error - unknown item 'CRYPT_PREFIX' (notify administrator) > configuration error - unknown item 'CRYPT_ROUNDS' (notify administrator) > configuration error - unknown item 'USE_TCB' (notify administrator) > configuration error - unknown item 'TCB_AUTH_GROUP' (notify administrator) > configuration error - unknown item 'TCB_SYMLINKS' (notify administrator) > configuration error - unknown item 'USERNAME_MAX' (notify administrator) > configuration error - unknown item 'GROUPNAME_MAX' (notify administrator) All of the above login.defs settings are Owl extensions. The above error messages mean that you also did not apply our patches to the shadow suite. :-( If so, you've dropped the tcb support from useradd(8) and from all other user management commands. You've also dropped our security fixes and security "hardening" enhancements, and more. In Owl-current, we have a total of 20 patch files to the shadow suite: owl!build:~/native/Owl/packages/shadow-utils$ wc *.diff 49 156 1542 shadow-188.8.131.52-alt-configure.diff 34 179 1347 shadow-184.108.40.206-alt-man.diff 39 147 1110 shadow-220.127.116.11-cvs-20041008-userdel.diff 40 191 1202 shadow-18.104.22.168-owl-chage-drop-priv.diff 153 535 3701 shadow-22.214.171.124-owl-check-reads.diff 53 186 1283 shadow-126.96.36.199-owl-create-mailbox.diff 152 552 3824 shadow-188.8.131.52-owl-crypt_gensalt.diff 19 72 583 shadow-184.108.40.206-owl-malloc-cast.diff 16 56 577 shadow-220.127.116.11-owl-man.diff 45 180 1300 shadow-18.104.22.168-owl-newgrp.diff 477 1750 12527 shadow-22.214.171.124-owl-pam-auth.diff 14 61 474 shadow-126.96.36.199-owl-pam_chauthtok.diff 219 820 6917 shadow-188.8.131.52-owl-restrict-locale.diff 2343 8390 55236 shadow-184.108.40.206-owl-tcb.diff 15 66 528 shadow-220.127.116.11-owl-tmp.diff 12 70 507 shadow-18.104.22.168-owl-userdel-path_prefix.diff 133 607 4195 shadow-22.214.171.124-owl-usergroupname_max.diff 12 65 533 shadow-126.96.36.199-owl-usermod-unlock.diff 11 55 405 shadow-188.8.131.52-owl-usermod-update-lstchg.diff 896 4384 27475 shadow-184.108.40.206-rh-owl-redhat.diff 4732 18522 125266 total If my guesses are correct, then what you have now is not quite Owl. It is Owl minus our shadow suite and with some of the other programs overwritten with the shadow suite implementations. To clean up this mess, you may "make uninstall" your shadow suite, then "make installworld" Owl over your system. If the "make uninstall" doesn't work or doesn't remove all of the files that were installed, you may nevertheless proceed with the "make installworld" and then use some "rpm -qal | sort", "find ... | sort", and "comm ..." commands to identify the extra non-Owl shadow suite files that you would have left lying on the system. You would need to remove those files. -- Alexander Peslyak <solar at openwall.com> GPG key ID: 5B341F15 fp: B3FB 63F4 D7A3 BCCC 6F6E FC55 A2FC 027C 5B34 1F15 http://www.openwall.com - bringing security into open computing environments Was I helpful?
