Invalid command GssapiCredStore

[jbreitman]

Apache 2.4.57 is complaining that GssapiCredStore does not exist.
I compiled mod_auth_gssapi version 1.6.5 and am not sure how to resolve this issue.

/usr/local/httpd-2.4.57/bin/apachectl configtest
AH00526: Syntax error on line 110 of /usr/local/httpd-2.4.57/conf/sites-enabled/ssl.conf:
Invalid command 'GssapiCredStore', perhaps misspelled or defined by a module not included in the server configuration

I have to comment out the GssapiCredStore to run the command below and you can see that function does not exist.
/usr/local/httpd-2.4.57/bin/httpd -L | grep mod_auth_gssapi.c
GssapiSSLonly (mod_auth_gssapi.c)

Check the config.log, and check what is the result of these two checks:
AC_CHECK_FUNCS(gss_acquire_cred_from)
AC_CHECK_FUNCS(gss_store_cred_into)

If they fail GssapiCredStore will not be available because HAVE_CRED_STORE will be unset:

mod_auth_gssapi/src/mod_auth_gssapi.c

Lines 1990 to 1994 in 796000a

	#ifdef HAVE_CRED_STORE
	AP_INIT_FLAG("GssapiUseS4U2Proxy", mag_use_s4u2p, NULL, OR_AUTHCFG,
	"Initializes credentials for s4u2proxy usage"),
	AP_INIT_ITERATE("GssapiCredStore", mag_cred_store, NULL, OR_AUTHCFG,
	"Credential Store"),

Thank you.
The README does say MIT krb5 (>=1.11), but I was using 1.10.

Glad it solved your problem
