Google Search says that many people are getting the same error when trying to compile various software packages:
http://www.google.com/search?q=undefined+reference+to+%60length_PA_ENC_TS_ENC%27 I have not taken the time to find a solution for you, but hopefully the above will help. As an aside: cosign's configure script does not use krb5-config. As a starting point, you may want to run "krb5-config --cflags" and add the output (if any) to the CFLAGS for cosign. Likewise, run "krb5-config --libs" and add the output to the LDFLAGS for cosign. For example, on my machine I would do: $ krb5-config --cflags $ krb5-config --libs -dynamic -Wl,-search_paths_first -lkrb5 -lk5crypto -lcom_err -lresolv $ LDFLAGS="-dynamic -Wl,-search_paths_first -lkrb5 -lk5crypto -lcom_err -lresolv" ./configure --enable-apache2=/usr/sbin/apxs --enable-krb=/usr ...however, this is just a random suggestion. I recommend that you go through the problems that other people have been having with other packages and see if you can find how they solved it. Also... have you successfully compiled something else using these Kerberos libraries? Best luck.
