Hello, I have an issue that I just cannot figure out. When using /bin/login and pam_krb5 on Redhat 7.2, I get the following output message in syslog and login fails: May 15 23:32:59 onyx login(pam_unix)[11384]: authentication failure; logname=bsf elton uid=500 euid=500 tty=pts/1 ruser= rhost= user=bsfelton May 15 23:32:59 onyx login[11384]: pam_krb5: authentication succeeds for `bsfelt on' May 15 23:32:59 onyx login[11384]: initgroups: Operation not permitted I understand the first line, this is a result of me adding *K* to my /etc/passwd file in place of x. This causes pam_unix to fail and then pam_krb5 is next in line. The last line is where I am clueless. What exaclty is going on here? I am using login configuration that came with pam_krb5 in 7.2. I have included it below. auth required /lib/security/pam_securetty.so auth required /lib/security/pam_nologin.so auth sufficient /lib/security/pam_unix.so shadow md5 nullok likeauth auth required /lib/security/pam_krb5.so use_first_pass account required /lib/security/pam_unix.so password required /lib/security/pam_cracklib.so password required /lib/security/pam_unix.so shadow md5 nullok use_authtok session required /lib/security/pam_unix.so session optional /lib/security/pam_krb5.so session optional /lib/security/pam_console.so Any help with this would be greatly appreciated!!!
