The following steps create the issue:
Set LD_LIBRARY_PATH to include apache's libraries:
export LD_LIBRARY_PATH=/path/to/apache-2.4/apache/lib:/lib64
Start apache server
Make request (as a client) with kerberos authentication requiring to run kinit
kinit -kt /path/to/kerberos.kt principal@REALM.COM
Error occurs due to:
kinit: relocation error: kinit: symbol krb5_get_init_creds_opt_set_pac_request, version krb5_3_MIT not defined in file libkrb5.so.3 with link time reference
Apache lib includes kerberos libraries which should be included after /lib64. Export /lib64 before apache's library directory. Refer to Solution
``` export LD_LIBRARY_PATH=/lib64:/path/to/apache-2.4/apache/lib ```
