(This is a bit offtopic, but I have only a few resources to turn to) I have pam_ldap working fine, but when I install pam_ccreds and insert ccreds''s example config, it no longer works: CCRED''s example: #-------------------------------------------------------------------------------------- other auth [user_unknown=ignore default=done] \ /lib/security/pam_unix.so other auth [authinfo_unavail=ignore success=1 default=2] \ /lib/security/pam_ldap.so try_first_pass other auth [default=done] /lib/security/pam_ccreds.so action=validate use_first_pass other auth [default=done] /lib/security/pam_ccreds.so action=store other auth [default=done] /lib/security/pam_ccreds.so action=update other account [user_unknown=ignore default=done] /lib/security/pam_unix.so other account [authinfo_unavail=ignore default=done] /lib/security/pam_ldap.so other account [default=done] /lib/security/pam_permit.so other session required /lib/security/pam_unix.so other password required /lib/security/pam_ldap.so #-------------------------------------------------------------------------------------- Ubuntu uses /etc/pam.d/common-auth/password/account/session The default format is for example auth required pam_ldap.so So, ccred''s example is not in the correct format? Connecting with ldap without these (ccreds) changes works fine. Error message I see after trying to "tweak" the example: Jun 15 14:54:53 localhost login[4747]: (pam_unix) check pass; user unknown Jun 15 14:54:53 localhost login[4747]: (pam_unix) authentication failure; logname=LOGIN uid=0 euid=0 tty=tty1 ruser= rhostJun 15 14:54:55 localhost login[4747]: FAILED LOGIN (1) on `tty1'' FOR `frans'', Authentication service cannot retrieve authentication info.
