# krb\_set\_tkt\_string(3)

set Kerberos ticket cache file name

## NAME

krb\_set\_tkt\_string - set Kerberos ticket cache file name

## SYNOPSIS

```
#include <krb.h>
```

**void krb\_set\_tkt\_string(filename)** **char \*filename;**

## DESCRIPTION

*krb\_set\_tkt\_string* sets the name of the file that holds the user's cache of Kerberos server tickets and associated session keys.

The string  *filename* passed in is copied into local storage. Only MAXPATHLEN-1 (see \<sys/param.h\>) characters of the filename are copied in for use as the cache file name.

This routine should be called during initialization, before other Kerberos routines are called; otherwise the routines which fetch the ticket cache file name may be called and return an undesired ticket file name until this routine is called.

## FILES

- /tmp/tkt\[uid\]

  default ticket file name, unless the environment variable KRBTKFILE is set. \[uid\] denotes the user's uid, in decimal.
