I was configuring some AuthnProviderAliases today and I want to add kerberos to it. The problem is that when I added kerberos apache wouldn't restart and I got the following error in my syslog:
May 3 15:27:09 Himeji kernel: [18882.364760] apache2[13774]: segfault at 4 ip b72dacdd sp bfd4f5f0 error 4 in mod_authn_alias.so[b72da000+2000]
I have followed the syntax on http://httpd.apache.org/docs/2.2/mod/mod_authn_alias.html#authnprovideralias and I have the following for ldap which give no errors:
<AuthnProviderAlias ldap ldapa>
AuthLDAPBindDN cn=apache,cn=Users,dc=samba,dc=my,dc=domain
AuthLDAPBindPassword Test123
AuthLDAPURL "ldaps://192.168.142.1:636/dc=samba,dc=my,dc=domain?sAMAccountName"
AuthType Basic
</AuthnProviderAlias>
And the following for kerberos:
<AuthnProviderAlias kerberos kerb>
AuthType Kerberos
KrbMethodNegotiate on
KrbMethodK5Passwd off
KrbSaveCredentials off
KrbAuthRealms SAMBA.MY.DOMAIN
Krb5Keytab /etc/apache2/http.keytab
</AuthnProviderAlias>
However the kerberos part doesn't work. Is it because kerberos is not a baseProvider?
